FAQ
Do you provide the full source code?
Yes. You get the complete, well-structured source code with a clean commit history in every package.
Which Python framework do you use?
FastAPI. It's modern, fast, and produces clean, well-documented APIs with automatic interactive docs (Swagger/OpenAPI).
Can you integrate a database?
Yes. I work with PostgreSQL and design the data layer properly as a qualified Database Administrator. Database integration is included in the Standard and Premium packages.
Do you set up authentication?
Yes. I can add secure JWT authentication with password hashing. It's included in the Premium package or available as an extra on any package.
Can you deliver the project in Docker?
Yes. I can provide a Docker-ready setup so your API runs in a reproducible environment. Included in Standart and Premium.
What do you need from me to start?
A short description of your project, the endpoints or features you need, and any existing database schema or requirements. If you're not sure, just message me and I'll help you scope it.
What if I need more endpoints than a package includes?
No problem — you can add extra endpoints via the gig extras, or message me for a custom offer tailored to your project.
