Building a suite of field data collection mobile apps for the CropGPT platform, used by agricultural agents across
Africa, South America, and Southeast Asia. Apps include GPS photo capture, offline-first upload queues, device
qualification, and crop calendar tools — designed for low-literacy users in remote, low-connectivity environments.
React Native (Expo SDK 56), TypeScript, pnpm monorepo, Turborepo
AWS Cognito for authentication; AWS S3 for photo upload (presign → PUT → register pipeline)
Offline queue: photos captured with no signal upload automatically on reconnect
Targeting Android (phone + tablet) and iOS (iPhone + iPad)

Full-stack ownership of production mobile apps: architecture, feature development, testing, and release. React,
TypeScript, Supabase, RevenueCat, Stripe, Paystack; deployment via App Store Connect and Google Play. Landing
pages (driveswift.app, dealfusion.co.uk) deployed with Git and Netlify. User support and iteration from real feedback.
