I will build a rest API backend with fastapi and postgresql
Richard O.
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.
---------------------------------
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
---------------------------------
THE STACK
---------------------------------
FastAPI / PostgreSQL / SQLAlchemy async / asyncpg / Alembic / Docker / JWT
---------------------------------
TO GET STARTED
---------------------------------
1. What your API needs to do
2. What data it need

I'm a Python backend engineer with hands-on experience building and deploying real production systems. I specialize in FastAPI, SQLAlchemy, PostgreSQL, and Docker. I've built a deployed URL shortener, published an open source auth library to PyPI, and I'm currently building a multi-tenant project management platform. I build things that actually work.

FAQ
What am I actually getting?
A working API you can use immediately—clean structure, solid endpoints, and something you won’t need to rebuild in a month.
Is this custom or just a reused template?
I reuse good patterns, not copy-paste projects. The structure and logic are shaped around what you actually need.
Will this hold up as my app grows?
eah—pagination, filtering, and sane database design are built in from the start so it doesn’t fall apart once you have real data.
Will I understand it / be able to maintain it later?
Yes. The code is organized and readable, and you’ll have docs. You (or another dev) won’t be stuck trying to decode it later.
