I will develop Python backend APIs with FastAPI

Professional REST API development with FastAPI and Python.

What you will get:
- REST API built with FastAPI (Python 3.11)
- PostgreSQL database integration using SQLAlchemy ORM
- JWT authentication with refresh tokens and role permissions
- Request/response validation with Pydantic schemas
- Auto-generated OpenAPI/Swagger documentation
- Docker and Docker Compose configuration
- Automated tests with pytest (80%+ coverage)
- Clean architecture, properly documented

I have built backend services for production use in fintech and Web3. Ready to deploy, easy to extend.

Tell me what endpoints you need and what data you are working with.
