Over deze dienst

I will build, fix, test, and release your mobile app for iOS and Android.


I specialize in React Native, Expo, Flutter, Swift, Kotlin, Firebase, Supabase, Node.js, PostgreSQL, Stripe, RevenueCat, and app store deployment.


This gig is best for clients who already have an app, MVP, design, or idea and need help turning it into a stable, production-ready product.


I can help with:

- React Native, Expo, or Flutter app development

- iOS and Android bug fixing

- App Store and Google Play release

- Firebase or Supabase integration

- API integration

- Login/authentication

- Stripe, RevenueCat, and in-app purchases

- Performance optimization

- Build errors and deployment issues

- Backend API development

- Admin dashboard or web app integration


Before starting, I will review your app, requirements, design, or existing codebase and explain what needs to be done clearly.


Please contact me before placing an order so I can confirm the scope, timeline, and best package for your project.
