Mobile App
Mobile commerce in emerging markets means unreliable connectivity. I built a React Native app with offline-first architecture—users can browse products, add to cart, and queue orders even without internet. The app syncs when connectivity returns, handling conflicts gracefully.

The Problem
Users in our target market have spotty internet. Traditional e-commerce apps fail completely when offline, losing sales.
The Solution
Built offline-first with local SQLite storage, optimistic UI updates, and background sync. Orders queue locally and submit when connectivity returns.
Technical Challenges
1
Designing conflict resolution when offline edits clash with server state
2
Optimizing app size for users with limited storage and slow download speeds
3
Implementing push notifications that work across Android fragmentation
