About this Gig

I build cross-platform Flutter mobile apps for iOS and Android with fully integrated in-app purchases and subscriptions one-time purchases, recurring plans, consumables, and restore-purchase flows through App Store, Google Play Billing, or RevenueCat.


What I deliver:

  • Flutter app development for iOS and Android from a single codebase
  • In-app purchase and subscription integration (App Store Connect, Play Console, RevenueCat, Stripe)
  • Firebase backend: auth, Firestore, push notifications, analytics
  • Node JS backend integration and SaaS MVP builds
  • Clean, scalable architecture (Provider, Riverpod, or Bloc), Dart development
  • React Native app development for cross platform projects
  • App store submission support for Apple and Google Play
  • Bug fixes, performance audits, and existing app repairs


Whether you need a new Flutter app built from scratch, in-app purchases added to an existing app, or a broken purchase flow fixed, I handle the full cycle UI to backend to store deployment.


Message me your app idea or codebase and I'll scope it fast.
