Message

At Upande, I build and maintain production apps for agribusiness clients, spanning Python/Frappe back ends and React and React Native front ends. I own each app from data model and API through tests, migrations, UI, and deployment, with shared code configured for different client sites.

On the Irrigation Scheduling Engine & Offline Field App, I rebuilt the scheduling engine as testable modules, fixing a bug that left 819 of 836 weekly plans without data. I also shipped an offline-first mobile app with 23 screens, where saved records queue in SQLite and sync later.
