Flutter apps usually break in the boring places: Firebase rules, API responses, payment states, push notifications, app-store builds, and the logic between screens.
I work as a Flutter Developer for Android/iOS apps where the goal is not just a working preview, but a clean, testable app clients can launch.
I build and improve mobile apps using Flutter, Dart, FlutterFlow, React Native, BLOC/Riverpod state management, Firebase, Supabase, REST APIs, payments, real-time chat, push notifications, and App Store / Play Store deployment workflows.
My best fit is usually one of these situations:
โข You have a Figma design and need it converted into a real Flutter or FlutterFlow app.
โข Your FlutterFlow app is partially built, but the Firebase, API, payment, or app logic is stuck.
โข Your Flutter app needs bug fixing, performance cleanup, UI polish, or redeployment.
โข You need an MVP for Android/iOS, but you want the structure clean enough to grow after launch.
โข You want AI features such as ChatGPT/OpenAI API, AI chat, AI assistants, or automation inside a mobile app.
What I can handle:
โข Flutter mobile app development for Android and iOS
โข FlutterFlow app development for MVPs, SaaS apps, marketplaces, booking apps, and dashboards
โข Firebase setup: Authentication, Firestore, Storage, Cloud Functions, security rules, and push notifications
โข Supabase setup: auth, database, APIs, and app integration
โข REST API and third-party integrations
โข Stripe, Razorpay, PayPal, in-app purchases, and subscription flows
โข Real-time chat, booking flows, order tracking, maps, user profiles, admin panels, and notification systems
โข App Store and Google Play release support
Common app types I work on: eCommerce and marketplace apps, restaurant and food delivery apps, booking and service apps, dating and social apps, education apps, health and fitness apps, SaaS MVPs, and AI-powered mobile apps.
Clients usually hire me when they need someone who can look beyond the screen design and make sure the app logic, backend, integrations, and launch steps are actually connected properly.
If you need a Flutter Developer who can build, fix, or launch your Android/iOS app with Flutter, FlutterFlow, Firebase, APIs, and payments handled cleanly, send me the app details and I will suggest the best next step
