You will get FastAPI backend or REST API with auth, DB and clean structure
Project details
I build clean, scalable backend systems using Python and FastAPI.
If you need a reliable REST API for your application, I can design and develop it with a clear structure, proper validation, and production-ready code.
I focus on simplicity, performance, and maintainability — not just making it work, but making it solid and easy to extend.
What I can help you with:
REST API development
Database integration (PostgreSQL, etc.)
Authentication systems (JWT, login/register)
Clean architecture and structured code
API documentation (Swagger/OpenAPI)
You’ll get a backend that works, is easy to understand, and ready to scale.

About Robert Mihai
Python Backend Developer | APIs, Automation & AI Systems
Torrox Costa, Spain - 4:14 am local time
My focus is FastAPI and REST APIs: authentication systems, PostgreSQL integration, automation workflows, and AI-powered features. I've built a document intelligence platform with async processing and full test coverage, and a real-time AI governance engine used to evaluate and filter model outputs at scale — both from scratch, both production-ready.
I write tested, documented code. I don't disappear mid-project. If something is unclear, I ask before I build, not after.
Good fit if you need: a backend for your SaaS MVP, an internal API for automation, or Python logic connected to an AI model.
Not a good fit if you need a full-stack developer or someone to clone a template.
