FAQ
Can you deploy the backend to a VPS or cloud server?
Yes. I can deploy your FastAPI backend using Docker on a VPS or cloud server, configure PostgreSQL, set up environment variables, and make your backend production-ready.
Can you build backend APIs for AI applications?
Yes. I build secure and scalable FastAPI backends for AI applications, SaaS platforms, admin panels, and mobile apps, including authentication, database design, third-party integrations, and production deployment.
Can you build a complete FastAPI backend from scratch?
Yes. I can build a production-ready FastAPI backend with PostgreSQL, JWT authentication, REST APIs, database design, Docker, Alembic migrations, and API documentation.
Can you fix or upgrade an existing FastAPI project?
Absolutely. I can fix bugs, improve performance, refactor code, add new APIs, optimize database queries, and extend your existing FastAPI backend without rebuilding the project.
Do you integrate third-party APIs?
Yes. I can integrate payment gateways, Firebase, OpenAI, Google APIs, email services, SMS gateways, cloud storage, and other third-party REST APIs based on your project requirements.
What do you need before starting the project?
Please share your project requirements, API specifications (if available), database structure, existing source code (if any), and any third-party services you need to integrate. If you only have an idea, I can help you plan the backend architecture.
