I build mobile apps in Flutter for Android and iOS, and I build the backend behind them myself. One person owns the app, the API, the database and the deployment, so nothing gets lost between a mobile developer and a backend developer.

What you get:

• A Flutter app for both Android and iOS, from one codebase • A REST API with authentication, roles and validation, in NestJS or FastAPI • Database design on PostgreSQL or MySQL • An admin panel to manage users, content and orders • Push notifications, file and image upload, and real-time features like chat where the app needs them • Payments with Stripe if you need them • Deployment of the backend to your server, and help getting the app onto the stores

I have built this kind of system before: Armorix, a vehicle protection platform with four user roles and a Flutter app, and Tradeeaze, a UK marketplace connecting businesses with tradespeople.

Tell me what your app needs to do and who uses it, and I'll come back with a plan, a timeline and a fixed price.
