FAQ
What technologies do you use?
I primarily use FastAPI, Python, PostgreSQL, MySQL, SQLite, SQLAlchemy, Pydantic, JWT Authentication, Docker, and REST API best practices.
Can you connect the API to a database?
Yes. I can integrate your API with PostgreSQL, MySQL, SQLite, or other supported databases.
Will the API include documentation?
Yes. FastAPI automatically generates Swagger UI and ReDoc documentation for easy testing and integration.
Do you provide authentication and authorization?
Yes. I can implement JWT authentication, API Keys, role-based access control, and user management systems.
Can you deploy the API?
Yes. I can deploy your application to Railway, Render, VPS servers, Docker containers, or cloud platforms.
Can you work with an existing project?
Absolutely. I can add new features, fix bugs, optimize performance, or improve existing APIs.
Do you provide source code?
Yes. You will receive clean, well-structured, and documented source code upon project completion.
What if I need revisions?
Revisions are included according to the package you select. Additional revisions can be discussed if needed.
Can you build third-party integrations?
Yes. I can integrate payment gateways, email services, external APIs, AI services, and more.
How long will the project take?
Delivery time depends on complexity. Simple APIs usually take 1-3 days, while larger systems may require more time.
