About this gig

Most Flutter developers build screens.


I build real mobile products.



If you're a startup or business, you don't just need a Flutter app; you need a scalable backend, secure authentication, and an architecture that won't break when your user base grows.


I specialise in creating production-ready mobile apps with Flutter and Firebase that are fast, secure, and ready to scale.



Whether you're launching an MVP or a full SaaS product, I'll help you design, build, and ship a real mobile app, not a demo.



What I build


  1. Flutter apps for iOS & Android
  2. Login & user roles
  3. Firebase (Auth, Firestore, Storage, Functions)
  4. Payments & subscriptions
  5. Push notifications
  6. Admin dashboards
  7. API integrations
  8. AI chat & automation (optional)
