I will design your postgresql database with sqlalchemy and alembic
Backend Systems, Open Source Author
About this Gig
Need a backend built properly from the ground up? I will deliver a
production-ready REST API you can actually deploy not a tutorial
project with duct tape holding it together.
I have shipped FastAPI backends for live products handling real users,
concurrent requests, and multi-tenant data isolation. I know what
breaks in production and I build around it from day one.
WHAT YOU GET
---------------------------------
- Fully async REST endpoints CRUD, filtering, sorting, pagination
- PostgreSQL database with SQLAlchemy ORM and Alembic migrations
- JWT authentication access and refresh token flow included
- Input validation and proper error handling throughout
- Docker setup Dockerfile and docker-compose ready to deploy
- API documentation auto-generated via FastAPI
- Clean, commented source code that is yours to keep
- Deployable to Railway, Render, or your own server
