FAQ
Can you build both the Flutter app and the FastAPI backend?
Yes! I handle the full stack — Flutter mobile app, FastAPI REST backend in Python, and PostgreSQL or Firebase database. You get one developer for the entire project.
Which database do you recommend — PostgreSQL or Firebase?
It depends on your project. PostgreSQL is better for complex data and relational structures. Firebase is better for real-time features and quick auth setup. Message me and I'll recommend the right one for you.
Will the FastAPI backend be deployed on a server?
Yes, in the Premium package the API is deployed and live. For Basic and Standard I deliver the full working code — you can deploy it yourself or we can discuss server setup separately.
Do I get the full source code?
Yes — complete Flutter app code and FastAPI backend code are yours after delivery.
Can you fix my existing Flutter app or broken FastAPI?
Absolutely. Share the issue and I'll diagnose and fix it within 24–48 hours.
What do you need to get started?
Your app idea or requirements, any design references, and database/server credentials if you already have them set up.
Can you integrate third-party APIs into my app?
Yes — payment gateways, maps, social login, SMS/email services, and more.
