I will integrate firebase, supabase, or API into your flutter app
Temmy T.
About this gig
Need a backend connected to your Flutter or FlutterFlow app?
I integrate Firebase, Supabase, REST APIs, and third-party services into mobile apps so they work reliably in production.
I set up authentication, databases, storage, cloud functions, and API connections with clean architecture and proper error handling. No shortcuts, no fragile workarounds.
What I integrate:
- Firebase: Auth, Firestore, Cloud Functions, Storage, FCM push notifications, Analytics
- Supabase: Auth, PostgreSQL database, Row Level Security, Storage, Edge Functions
- REST API and GraphQL connections with proper state management
- Stripe, RevenueCat, and in-app purchase payment flows
- Google Maps, geolocation, and location services
- File uploads, camera, image compression
- Role-based access control and admin logic
- Real-time data sync and offline-first architecture
I have built and maintained production backends for social platforms, field inspection tools, and business dashboards using both Firebase and Supabase. I understand how to structure data, secure access, and keep things scalable from the start.
Message me with your project details.

I’m a FlutterFlow & Flutter developer helping founders and businesses build reliable, production-ready mobile apps. I turn ideas, Figma designs, and half-built products into scalable Android/iOS apps with clean architecture and smooth UX. I handle FlutterFlow custom actions, Flutter development, Firebase/Supabase backend setup, API integrations, payments, bug fixes, and App Store/Play Store launch support. I also use AI-assisted workflows with Cursor to ship faster, stay organized, and maintain high code quality without sacrificing stability.

FAQ
Can you integrate Firebase into my existing Flutter or FlutterFlow app?
Yes. I regularly add Firebase services to existing apps without disrupting current functionality.
Firebase or Supabase — which should I use?
Firebase is better for real-time apps, push notifications, and rapid prototyping. Supabase is better for SQL-based data, complex queries, and cost control at scale. I can advise based on your project.
Can you connect my app to a custom REST API?
Yes. I handle API connection, authentication headers, error handling, and data parsing with clean state management.
Do you set up security rules and role-based access?
Absolutely. Every backend I set up includes proper security rules, row-level security, or role-based access control depending on the platform.
Can you add Stripe or payment processing?
Yes. I integrate Stripe, RevenueCat, and in-app purchases for subscriptions, one-time payments, and marketplace payouts.
Will the integration work with offline-first architecture?
Yes. I can set up local caching and sync logic so your app works reliably even without internet connectivity.
