Cyol Farm Management Application

The problem

Farm teams operating in low-connectivity regions across Africa needed reliable cultivation-to-harvest tracking without depending on a live connection.

What I built

An offline-first React Native application enabling farm teams to track crops from cultivation through harvest, syncing seamlessly once connectivity returns.

Architecture overview

• Local-first client architecture using WatermelonDB + SQLite with background sync against a NestJS backend
• Built for genuinely low-connectivity conditions rather than treating offline as an edge case
• React Native UI built with NativeWind and React Native Paper for a responsive, native feel
