Features for BlackBerry 10’s Notes, Tasks, music, video and pictures apps, then Notes and Tasks on Android, and list scrolling fast enough to earn a Performance Champion award. **Result.** List scrolling held at ~60 fps, earning a Performance Champion award. Both apps now have 1M+ downloads each on Google Play.

## How I work

- **Decisions in writing.** Specs, decision logs and API docs your team can review, and keep after I leave.
- **Measure, then change.** Eval harnesses and tuning runs before a prompt, model or threshold changes.
- **Safe to ship.** Human review before production writes. Staged rollouts with a rollback ready.
- **Remote, AI-assisted.** Remote since 2019. Coding agents for speed; people make the calls and review what ships.

# Gemini Golf Coach

> A walk-up AI golf coach for Google’s Gemini audio launch. Cameras measure your swing, Gemini picks the one thing to fix, and a voice coach talks you through it while the replay shows you the moment.

**TL;DR.** Case study of work by Ali Farooq, Product Engineer, for Google, Gemini audio launch (4 wks · live Sep 24, 2026). **Ali's role.** UI, workflow, coaching, tests. **Outcome.** 191 guests coached. **By the numbers.** 191 guests coached; 264 swings measured; 4 wks from first code to event night; 9.5 h live on two bays.

Web version at https://www.alifarooq.io/work/golf/, updated 2026-10-17.

Written by Ali Farooq in the first person, so "I" below means Ali.

## At a glance

- **Client.** Google, Gemini audio launch
- **Built with.** Handstand, San Francisco
- **Timeline.** 4 wks · live Sep 24, 2026
- **My role.** UI, workflow, coaching, tests
- **Stack.** MediaPipe · Gemini 3.8 Live · TS · Python
- **Outcome.** 191 guests coached

## Summary

- **Challenge.** Guests who’d never held a club needed real, spoken coaching seconds after a swing, live at a launch event.
- **What Ali owned.** The UI, the guest workflow, the coaching and the tests. Made sure it all worked together, on site through event night.
- **Result.** **191 guests coached** across two bays in one night, each leaving with a personal recap video.
- **Shows.** AI and LLM · voice AI · real-time · live ops
- **Stack.** MediaPipe, Gemini, TypeScript, Python
- **Relevant if you're hiring for.** AI and LLM features, Voice AI, Real-time and computer vision, Live operations

## By the numbers

- **191** guests coached
- **264** swings measured
- **4 wks** from first code to event night
- **9.5 h** live on two bays

## See it in action

- **A guest’s recap video, showing their swing in slow motion with measured joints, angles and swing graphs.** Every guest left with this. A personal recap of their swing, rendered in the cloud while they were still at the bay and handed over by QR code. Every joint, angle and graph on screen is measured from the cameras, not generated. (Recap video · 33 s · Gemini Audio Live, Sep 24, 2026) Watch it at https://www.alifarooq.io/media/golf/event-video.mp4
- **The Light Loom, a neon trace of two golf swings drawn from the guest’s silhouette and the path of the club.** And a Light Loom of their swings. A neon trace of each swing, built from the guest’s silhouette and the path of the club head. It drew itself on the finale screen and played again in the recap. (Light Loom · 12 s · Gemini Audio Live, Sep 24, 2026) Watch it at https://www.alifarooq.io/media/golf/light-loom.mp4

## Challenge

Google wanted its new Gemini audio models shown live at their launch event. Handstand built three walk-up demos, and golf was the hardest. A guest who may never have held a club steps into a netted bay, says their name, swings once, and needs coaching that is actually right. It has to be spoken aloud within seconds, while a queue waits behind them.

Everything was built around one rule. **The cameras measure, Gemini interprets.** The model never invents a number, a body position or a fault. If it can’t get a clean read, the coach says so.

## Constraints

- 4 wks from the first line of code to event night. Hardware arrived mid-build, and the final launch models landed about 48 hours before doors.
- Many guests had never swung a club, so each tip had to be one simple feel they could experience on the very next swing.
- The voice model can’t return structured data, so one model decides what to say and another one says it.
- Analysis takes several seconds, and nobody wants to stand there in silence.

## What I owned

Handstand built the installation as a team. Hardware, the recap video and the cloud platform were others’ work. I joined the golf build on the first day of code and owned everything the guest sees, hears and steps through.

- **The UI.** The kiosk screens guests watch, including the replay that jumps to the exact moment the coach is talking about and zooms in on that part of the body.
- **The workflow.** Every step of a guest’s visit, from saying their name to the second swing and the send-off, and what happens when a swing is missed or unreadable.
- **The coaching.** What the coach says and how it says it, from the prompts and the rules Gemini works within to the shape of every tip (challenge, fix, why it helps, recap).
- **The tests.** A tuning lab that scored prompts and models against recorded swings, plus the tests that kept the experience working as it changed every day.
- **Making it all work.** Brought the pieces together and tuned both bays on site through rehearsals and event night, with a recorder capturing every session so nothing went unexplained.

## How it works

`Two 120 fps cameras` → `MediaPipe pose` → **`Gemini analysis`** → **`Gemini Live voice coach`** → `Replay and recap video`

Computer vision does the measuring, with six swing phases and 24 body measurements per swing. Code then works out which faults those measurements actually support, and Gemini chooses from that shortlist. It can’t diagnose anything the cameras didn’t see, and its answer is checked before a word is spoken.

While Gemini thinks, the guest watches their own swing in slow motion from two angles, so the wait becomes part of the show. Then the coach talks them through one fix as the replay walks to each moment. On the second swing, the coach tells them whether it took.

*The stats screen shows measured angles only, never a guess.*

## Results

191 guests were coached across two bays in roughly 9.5 hours. Along the way, a few findings changed what shipped.

| What we found | What changed |
| :-- | :-- |
| Left to its own judgement, every model found a fault in every swing, even clean ones. | Gemini now chooses from faults the cameras actually saw. On a clean swing it says so, and on an unclear one it admits it. |
| A teaching pro reviewed the coaching and objected to its favourite tip, “keep your head still”, which opened 42% of its coaching. | Coaching now starts with the foundations (feet, stance, turn) and leaves the head for last. His review became the yardstick every prompt change was scored against. |
| In early tests the voice coach fumbled through 13 tool calls in 17 seconds before saying a word. | I gave the screen a script instead. The coach speaks right away, and the replay follows every word, in sync to the frame. |
| Missed swings left nothing to learn from once the night was over. | A recorder shipped on event night and kept every session, so the team could study what the cameras missed. |

## Skills this shows

| If you need | What I did here |
| :-- | :-- |
| AI your clients can trust | The coach only talks about what the cameras measured. When it can’t tell, it says so instead of guessing. |
| Proof before launch | I built a tuning lab to test prompts and models on recorded swings, so every change was judged on evidence, not gut feel. |
| An experience people enjoy | The replay walks to the exact moment the coach is describing, so every tip is something you can see. |
| Someone who owns it end to end | I owned the guest experience within Handstand’s build, from UI to coaching to tests, and delivered it for Google’s launch. |
| Calm when it’s live | I tuned both bays on event night and recorded every session so we could learn from it afterwards. |

## What this means for your project

- **Putting AI in front of your clients?** I make sure it only says what it can back up, and test it on real examples before anyone else sees it.
- **Is the experience the product?** I design for the person using it, with no spinners, no dead air, and every claim something they can see for themselves.
- **Small team, big scope?** I can own a whole piece of the product, from the AI to the screen it shows up on, and work to your team’s decisions.

# Screenshot-to-CRM pipeline

> A vision-LLM pipeline that reads screenshots of workflow submissions and performance reports, drafts structured records, and publishes them to a production CRM once a person signs off.

**TL;DR.** Case study of work by Ali Farooq, Product Engineer, for Private client, production CRM (Jul – Aug 2026). **Ali's role.** Sole engineer. **Outcome.** Full work days cut to a few hours.

Web version at https://www.alifarooq.io/work/screenshot-to-crm/, updated 2026-10-17.

Written by Ali Farooq in the first person, so "I" below means Ali.

- **Engagement.** Independent consulting

## Summary

- **Challenge.** Workflow submissions arrived as screenshots that had to be re-keyed into the client’s CRM.
- **What Ali owned.** Everything, from the vision-LLM pipeline and review interface to multi-model evaluation and a Chrome extension for full-page capture.
- **Result.** Work that took **full work days** by hand now takes **a few hours**. Every record is still approved by a person before it reaches production.

*[Image] Hand-drawn diagram of the six steps. A screenshot is classified, extracted and verified, then a person reviews each record before it is written to the production CRM.. Every document takes the same six steps. Nothing reaches the CRM until a person approves the draft.*

## Challenge

Workflow submissions and performance reports arrive as screenshots. Getting them into the client’s CRM as structured projects, roles and people records was manual work that took the team full work days. The two document types carry the same information in inverted layouts, either one project with many people or one person across many projects.

## Constraints

- A wrong contact or a wrong merge is far worse than a paraphrased title, and hard to undo once it reaches production.
- Screenshots are noisy, rotated and full of small text. Generic vision-to-JSON invents fields.
- The CRM’s pages are built from frames, so a normal browser screenshot captures a blank shell.
- Model confidence isn’t a calibrated probability.

## What I owned

I was the only engineer, from the first commit to production.

- **Vision pipeline.** Classify, extract, verify and enrich as queued jobs, over a closed Zod schema of entities and relationships.
- **Review interface.** Two review forms for the two document types, with versioned drafts and conflict detection.
- **Saving to the CRM.** Projects, roles and team links saved back into the client’s CRM from the server. The browser never holds the CRM token.
- **Evaluation.** A multi-model harness (Claude, Gemini, GPT) scoring classification and extraction against screenshots with checked, correct answers, with per-stage token and latency numbers. Every model ran through OpenRouter, so swapping one for another was a config change, not a rewrite.
- **Capture extension.** A Chrome MV3 side panel that captures full framed pages over the DevTools protocol and sends them for processing.

## Approach

The model reads the image and emits typed records in one call, validated against a closed vocabulary. There is no separate OCR step. Classification comes first. If a document can’t be identified with confidence, it stops there, before extraction or any database write.

Trust thresholds follow the value at stake in an error. Contact details and merges need more confidence than titles, and anything uncertain goes to review instead of the CRM. A lighter model classifies and a stronger one extracts, chosen after measuring that extraction drove most of the token usage and latency.

Fuzzy cross-document merging was built, then taken out of the production flow once it proved to be the riskiest kind of mistake.

## Results

- Work that took full work days of manual entry now takes a few hours.
- Getting screenshots in is now quick and orderly, and the structured records now power other services downstream.
- Structured records published to the client’s production CRM, each approved by a person first.
- Models chosen by testing them on screenshots with checked, correct answers, on accuracy, value and latency, not reputation.
- Full-page capture of the client’s framed pages, which standard browser capture couldn’t do.

## Skills this shows

| If your role needs | Evidence in this project |
| :-- | :-- |
| Document AI and extraction | Schema-constrained vision extraction. A document that can’t be identified with confidence stops before extraction. |
| LLM evaluation | A multi-model harness tested on screenshots with checked, correct answers, with per-stage token and latency numbers. |
| Human-in-the-loop design | A review UI with versioned drafts; nothing reaches production unreviewed. |
| Integrating with existing systems | Saving records back into the client’s CRM from the server, with clear errors when part of a save fails. |
| Browser tooling | An MV3 extension capturing framed pages over CDP. |

## What this means for your project

- **Have documents or screenshots people retype?** I’ll get them into your system as structured, reviewed records, and prove their accuracy and value before launch.
- **Worried about AI writing bad data?** I design where automation stops and a person approves, weighing the value at stake in each kind of decision.
- **Need one engineer to own it end to end?** This was a solo build, from browser capture to saving records back into the client’s CRM.

# Zircuit

> The system that schedules and runs proof jobs for an EVM-compatible ZK-rollup, plus its release engineering, from the first commits to public launch.

**TL;DR.** Case study of work by Ali Farooq, Product Engineer, for Zircuit (Sep 2022 – Feb 2026). **Ali's role.** Staff engineer. **Outcome.** Public mainnet, Aug 2024.

## Summary

- **Challenge.** If proving falls behind, a rollup’s state can’t advance and blocks can’t finalize.
- **What Ali owned.** The system that schedules and runs proof jobs (NATS, Go, Rust prover), prover upgrades and rollouts, and the public release pipeline.

**Architecture diagram.** The system I architected to schedule and run proof jobs, from block selection to batch proofs published on Ethereum. Drag to pan and scroll to zoom. Open it at https://link.excalidraw.com/readonly/hI5lHzpyHQanKGIy8WMx?darkMode=true

## Challenge

Zircuit is an EVM-compatible ZK-rollup with AI-powered security at the sequencer. Every batch has to be proved, and if proving falls behind, state can’t advance and blocks can’t finalize. The proving pipeline had to keep up, survive prover upgrades, and never hold up the chain.

## Constraints

- Proof jobs are long and expensive. A batch was proved every 5 to 6 hours, scaling to 8 to 10 provers under load.
- Every upgrade meant letting running jobs finish first, across staging, testing and production, with DevOps and external partners.
- Internal code had to stay private while the protocol code was published openly.

## What I owned

I was among the first four engineers, from the first commits to public launch.

- **Proof jobs.** Architected the system that schedules and runs proof jobs, with a NATS message bus, Go consumers running jobs concurrently, and a Rust prover as the worker.
- **Prover migrations.** Moved the proving stack from Halo2 to SP1, helped move the pipeline onto a new job-scheduling system, and owned prover upgrades in production.
- **Sequencer screening.** Built detectors on the sequencer-level security interface, including the blocklist and allowlist that decide which transactions are admitted.
- **Public release pipeline.** Automated publishing of the open-source monorepo from the private tree, stripping internal code before each push.
- **Release reliability.** Let running jobs finish before each upgrade, restarted the pipeline after, and ran the rollback when one failed.

## Approach

Never let proving hold up the chain. A durable message bus keeps producing batches separate from proving them, proof jobs run concurrently, and the pool of provers scales with load.

Upgrades are treated as operations. Let running jobs finish, upgrade, check it, restart, and keep a rollback ready.

## Results

- Zircuit’s Mainnet Phase 1 went live on August 5, 2024.
- Publishing to the open-source monorepo became about 2.5× faster, with internal code stripped automatically.
- Proving scaled to 8 to 10 provers under load.

Zircuit has since moved its L2 to Conduit, and the public repositories are kept for legacy purposes.

## Skills this shows

| If your role needs | Evidence in this project |
| :-- | :-- |
| Distributed systems | A NATS-based system that schedules and runs long proof jobs, scaled to 8–10 workers. |
| Release engineering | Upgrades that let running jobs finish, then restart, across three environments, with rollback. |
| Production migrations | Moved the prover from Halo2 to SP1 in production. |
| Security-sensitive systems | Transaction-screening detectors at the sequencer. |
| Open-source operations | An automated public mirror of a private monorepo. |

## What this means for your project

- **Running long, expensive jobs that can’t fall behind?** I design the concurrency so a slow step queues work instead of holding everything else up.
- **Upgrading critical infrastructure in production?** I treat upgrades as operations. I let running jobs finish, upgrade, check it, restart, and keep a rehearsed rollback ready.
- **Early team, no process yet?** I’ve built release management and incident response from scratch while shipping features.

## Challenge

A four-person team set out to build Macro, a tool for designing and running team processes as checklists, aimed at technical users. Teams build a process once, such as client onboarding, then run it as many times as they need. Each run assigns tasks to the right people and tracks progress, so managers can see where work gets stuck.

They needed a product in clients’ hands quickly, and a backend that wouldn’t need rewriting after launch.

*[Image] Mattermost Playbooks on a laptop and a phone, showing an incident channel and its checklist, under the Mattermost logo. Mattermost Playbooks today, on desktop and mobile. Image from mattermost.com.*

## Challenge

Mattermost is an open-source, self-hosted alternative to Slack, built in Go and React for teams that need control of their own data. In 2019 its plugin system was growing fast, and three gaps stood out. A server would install any plugin bundle it was given, with no way to prove the bundle came from Mattermost or hadn’t been changed. Admins had no central place to find plugins. And in a high-availability cluster, a plugin installed on one node didn’t reach the others.

In 2020 Mattermost started Incident Response, its first product built as a plugin, to help teams coordinate and measure how they handle incidents. It needed a foundation the team could build on quickly, and an API other teams and clients could rely on.

## What I owned

I joined the Toolkit and Workflows team in June 2019, working across plugins, the server and clustering, and moved to the Cloud Features team in August 2020.

- **Plugin signing.** Designed and built signature verification for plugins across the [server](https://github.com/mattermost/mattermost/pull/13017), [web app](https://github.com/mattermost/mattermost-webapp/pull/4145) and [Redux](https://github.com/mattermost/mattermost-redux/pull/972), with a setting to require signatures and GPG public keys the server trusts.
- **Signed releases.** Taught the release bot to split plugin binaries by platform, sign them and upload them ([matterbuild #17](https://github.com/mattermost/matterbuild/pull/17)), and made server packaging fail if a bundled plugin’s signature didn’t verify ([#13629](https://github.com/mattermost/mattermost/pull/13629)).
- **Plugin Marketplace.** The server API that proxies the upstream marketplace and merges in local plugins ([#11977](https://github.com/mattermost/mattermost/pull/11977)), listings limited to the versions a server supports ([marketplace #20](https://github.com/mattermost/mattermost-marketplace/pull/20)), and a local-only fallback when the upstream is off or unreachable ([#13250](https://github.com/mattermost/mattermost/pull/13250)).
- **Clusters and the plugin API.** Cluster events that sync plugin installs and removals across nodes ([#11611](https://github.com/mattermost/mattermost/pull/11611)), Prometheus metrics for plugin API calls and hooks ([#13825](https://github.com/mattermost/mattermost/pull/13825)), and direct database access for plugins ([plugin-api #46](https://github.com/mattermost/mattermost-plugin-api/pull/46)).
- **Incident Response, now Playbooks.** Built the first version, from [PR #1](https://github.com/mattermost/mattermost-plugin-playbooks/pull/1), which set up the plugin’s API handler, store and models, to the [slash command](https://github.com/mattermost/mattermost-plugin-playbooks/pull/6) that starts an incident, the [incident details panel](https://github.com/mattermost/mattermost-plugin-playbooks/pull/11), [team scoping](https://github.com/mattermost/mattermost-plugin-playbooks/pull/18) and [playbook templates](https://github.com/mattermost/mattermost-plugin-playbooks/pull/56).
- **REST API, docs and Go client.** Wrote the REST API section of the [technical spec](https://docs.google.com/document/d/1Kp2PmE8CDNUSUiviui4GhL51z5OmYf5QqrcxFu2YFJU/edit?tab=t.0#heading=h.gmdh3ysa72mw), then the [OpenAPI spec](https://github.com/mattermost/mattermost-plugin-playbooks/pull/177) and the official [Go client](https://github.com/mattermost/mattermost-plugin-playbooks/pull/169), and brought the endpoints in line with them.

On Cloud Features I shipped features for Mattermost Cloud, and throughout I mentored community contributors and junior engineers.

*[Image] Mattermost Playbooks showing a run as collapsible checklist sections, each with tasks and due dates*

*Playbooks today. Each run is a set of checklists with owners and due dates, grown from the incident checklist in the first versions. Image from mattermost.com.*

## Approach

“A mark of a good API design is that it is easy to use and hard to misuse.” That was the first line of the design discussion in my [Go client proposal](https://github.com/mattermost/mattermost-plugin-playbooks/pull/169), and it shaped everything else.

**Agree on the contract first.** The REST API section of the spec set the rules before any endpoint moved. POST creates, PUT replaces and PATCH updates part of a resource, and everything but POST is idempotent. Every list returns the same paginated envelope, and an empty list is an empty array, never null. Endpoints that only serve the plugin moved under /internal, so clients see only the API they can rely on.

**Then make the contract executable.** The [OpenAPI file](https://github.com/mattermost/mattermost-plugin-playbooks/pull/177) describes every endpoint with curl examples, served with Redoc. The [Go client](https://github.com/mattermost/mattermost-plugin-playbooks/pull/169) follows the conventions of Stripe’s and GitHub’s Go clients. The endpoints were then brought in line, with [standard error responses](https://github.com/mattermost/mattermost-plugin-playbooks/pull/206) and [paginated lists](https://github.com/mattermost/mattermost-plugin-playbooks/pull/213).

*The OpenAPI docs from PR #177, served with Redoc, and one of their curl samples. Screenshots from the pull request.*

**For signing, trust nothing by default.** Marketplace plugins are always verified, and once signatures are required, only signed Marketplace plugins install at all. Signing happens in the release tooling, so no one signs by hand, and packaging the server fails if a bundled plugin doesn’t verify.

## Results

- Plugin signing shipped in the Mattermost server, and it is still how admins verify plugins, as [Mattermost’s docs](https://docs.mattermost.com/developers/integrate/plugins/using-and-managing-plugins#plugin-signing) describe.
- Incident Response, the plugin I started in March 2020, grew into [Mattermost Playbooks](https://github.com/mattermost/mattermost-plugin-playbooks), which teams use to handle incidents. Mattermost features it in its [demo library](https://mattermost.com/resources/learn/demo-library/playbooks-incident-response/).
- The REST API conventions became a template other plugin teams followed.
- 145 merged pull requests across 10 repositories, all reviewed in the open.

## Skills this shows

| If your role needs | Evidence in this project |
| :-- | :-- |
| Platform and plugin systems | Plugin signing, the Marketplace API and cluster-wide plugin sync in Mattermost’s server. |
| API design | REST conventions, an OpenAPI spec and a Go client, designed together. |
| Security | Signature verification for third-party code, from release tooling to install. |
| Starting from zero | The first pull request of a product that now ships as Mattermost Playbooks. |
| Open source | 145 merged pull requests, reviewed in public. |

## What this means for your project

- **Building a platform other teams extend?** I design the extension points, the docs and the client together, so other teams can build on it without waiting on me.
- **Running code you didn’t write?** I’ve built signing and verification from release tooling to install time, so a server only runs what it can prove is genuine.
- **Starting a new product inside a large codebase?** I’ve built one from its first pull request and set the API conventions it grew on.

## Challenge

Zenreach helped brick-and-mortar merchants market to the guests who walked in, using WiFi presence to tell returning visitors from first-timers. Merchants needed those insights and their campaigns on their phones, and the data pipeline behind them had to keep up with 20,000 locations.

## What I owned

- **Mobile app.** Tech lead for the React Native merchant app, shipped to the iOS App Store and Google Play.
- **Mobile delivery.** CI/CD with BuddyBuild and Bitrise, plus CodePush to send updates straight to devices.
- **Presence pipeline.** Go and Kafka microservices with Protobuf messages, ingesting WiFi presence data from 20,000 merchant locations to tell returning from first-time walk-ins and trigger campaigns.
- **Operations tooling.** The tools to run and debug that pipeline.

## Results

- The merchant app shipped to both the App Store and Google Play.
- Updates reached devices through CodePush without waiting on store review.
- The presence pipeline served 20,000 merchant locations.

Zenreach is now Adentro.

## Challenge

Notes and Tasks are the apps people open many times a day. Notes holds to-do lists, meeting action items and the weekly shopping list. Tasks turns those into due dates and reminders, sorted by date or priority. Both sync with work email over Exchange ActiveSync, so a note written on the phone shows up in Outlook.

On BlackBerry 10, a brand-new platform running on 2013-era hardware, they had to feel instant. Long lists are where people notice a dropped frame first.

*BlackBerry Hub+ Notes for Android. Every note in one list, and edits made on the fly. Screenshots from Google Play.*

## What I owned

- **Notes and Tasks features.** Built features for the BlackBerry 10 Notes and Tasks apps in C++ and Qt.
- **List performance.** Held list scrolling at about 60 fps, which earned BlackBerry’s Performance Champion award.
- **Music, video and pictures.** Worked on the BlackBerry 10 music, video and pictures apps, as technical prime for media playback.
- **Android.** Moved with the apps to Android as an Applications Developer II.

## Results

- List scrolling held at about 60 fps in Notes and Tasks.
- A Performance Champion award for that work.
- Features that shipped with BlackBerry 10 platform releases.
- Both apps are still on Google Play today as part of BlackBerry Hub+, with more than a million downloads each.

## Skills this shows

| If you need | What I did here |
| :-- | :-- |
| An app that feels fast | Kept list scrolling at about 60 fps on 2013 hardware, and won an award for it. |
| Native mobile experience | C++ and Qt on BlackBerry 10, then Android. |
| Shipping to a platform schedule | Built features for Notes, Tasks and the media apps that landed with BlackBerry 10 releases. |
| Software people use every day | Worked on apps that went on to more than a million downloads each. |

## What this means for your project

- **Is your app slow where people notice?** I profile on real hardware and fix the frames people feel, starting with lists and scrolling.
- **Shipping on a platform release schedule?** I’ve built features that had to land on an OS release date, across C++ and Android.
- **Building productivity software people use every day?** Small delays add up fast in apps people open dozens of times a day. I treat responsiveness as a feature.
