Mobile App Developer

I've built mobile apps for 10 years, mostly with React Native and Flutter, for small e-commerce shops that need one codebase across iOS and Android. I handle app-store submission, push notifications, and offline-friendly state management. I don't do native Swift/Kotlin development for platform-specific features — for that I bring in a native specialist. Comfortable scope is an app with 10-20 screens.
