FAQ
Can you work with my existing Flutter app or codebase?
Yes. I work on existing Flutter apps — adding features, fixing bugs, refactoring, or integrating APIs. Share your code before ordering and I'll confirm scope and timeline upfront.
Which package do I need for my project?
Starter Task: fixes or small features on existing app. Feature Module: 2–4 screens with NestJS or Firebase backend. Full App Build: complete app from scratch with backend and store deployment. Message me if unsure.
Do you handle both Flutter and the backend?
Yes — I own the full stack. Flutter frontend, NestJS REST API, Firebase, database, payments, real-time features, and deployment. One developer, no handoffs, consistent architecture throughout.
What architecture and state management do you use?
Clean architecture — MVVM, MVC, Repository pattern. State management with BLoC, Riverpod, GetX, or Provider. If you have an existing setup I follow it. All code is documented and modular.
Can you integrate Stripe, Agora, or third-party APIs?
Yes — Stripe payments, Agora audio/video, Google Maps, WebSocket chat, push notifications, and most REST APIs. Mention your integrations when ordering and I'll confirm they're covered.
What happens after delivery?
Revisions within scope are included — 2 Basic, 3 Standard, 5 Premium. I stay available for questions after delivery. New features outside scope get a separate quote.
