FAQ
What type of APIs can you build?
REST APIs for web apps, mobile backends, internal tools, automation workflows, and third-party integrations.
Which database do you work with?
PostgreSQL and Supabase primarily. SQLite for lightweight or offline-first systems.
Will I get API documentation?
Yes. FastAPI auto-generates interactive Swagger UI docs. You get a live documentation endpoint with every delivery.
Can you integrate my API with a frontend?
Yes. I also build Next.js frontends. If you need a full-stack solution, message me for a custom offer.
Is the code production-ready?
Yes. You get clean, modular Python with proper error handling, input validation, and environment variable management.
Can you deploy the API?
Basic deployment guidance can be given. Full deployment to Railway, Render, or AWS is available as an add-on.
