About this gig

Need a mobile app that works perfectly without internet?

I develop offline-first mobile apps that store data locally and sync automatically when online, ensuring reliability even in rural areas or poor connectivity zones.


Using Flutter or React Native, I create Android and iOS apps with offline databases, background sync, and seamless user experiences. Whether you need an offline e-commerce app, an education app, or a field service tool, I deliver fast, secure, and scalable solutions.

Key features I offer:

  • Local database & offline caching
  • Auto-sync on reconnection
  • Cross-platform or native builds
  • Firebase or custom API integration
  • Optimized for speed & storage


Perfect for businesses, NGOs, and startups who need apps that work anytime, anywhere. Lets build your offline-first solution today!
