Zenreach (now Adentro)

Problem

Zenreach helped brick-and-mortar merchants market to the customers 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. Figures on Adentro’s site today describe the current company, not this work.
