About this gig

Production-Grade Flutter Apps (iOS & Android)

I dont just write codeI build complete, scalable products. With 2+ years of production experience and a background as a Technical Lead, I bridge the gap between a beautiful UI and a rock-solid backend.

Most devs rely on "Firebase hacks." I offer Full-Stack Engineering: high-performance Flutter apps powered by professional backends (FastAPI/Django).

️ What You Get:

  • Clean Architecture: Scalable code using Riverpod, Get_it, and Auto_route.
  • Full-Stack Power: Custom APIs with FastAPI/Django, PostgreSQL, and Redis.
  • Cloud & Auth: Firebase (Google/Apple Sign-in), Firestore, and Push Notifications.
  • Monetization: Secure Stripe integration for subscriptions/payments.
  • Polished UX: Light/Dark modes, responsive layouts, and robust error handling.
  • Store Ready: APK/IPA builds and App Store/Google Play submission support.

The Developer Advantage:

I led architecture and mentored teams at Freeway. I apply enterprise-level precision to your projectensuring your app is a production-ready system, not just a prototype.
