I will build a clean rest API with fastapi and sqlalchemy with full crud
Federico M
About this gig
I build FastAPI backends that are clean, tested, and ready to ship not just boilerplate.
Every project follows SOLID principles, the Repository pattern, and proper separation of
concerns.
What you get:
- FastAPI with async endpoints
- SQLAlchemy 2.0 ORM (SQLite or PostgreSQL)
- Pydantic v2 schemas with full validation
- Auto-generated OpenAPI and Swagger docs
- Correct HTTP status codes and error handling
- pytest test suite (Standard and Premium)
Optional add-ons: JWT authentication, file uploads, background jobs, Docker, deployment to
Render.
Send me your data model and requirements and I will reply within 1 hour with a plan.

I am a Backend/Automation Engineer focused on data-driven systems (SQL + REST APIs + event-driven workflows). I designed and evolved a system with ~2,100 transactions/month, reducing the time per transaction from ~10 min to ~5 sec.
FAQ
Can you add authentication to an existing API?
Yes, JWT auth can be added to an existing FastAPI project. Message me with your current code and I will give you an estimate.
Do you write tests?
Yes, every Standard and Premium delivery includes a pytest suite covering the main happy paths and edge cases.
SQLite or PostgreSQL?
SQLite for simple apps and free-tier deploys. PostgreSQL for production workloads. I support both, just tell me your preference.
