You will get a Secure REST API with FastAPI and PostgreSQL
Project details
I’ll deliver a clean, secure, and production-ready REST API using FastAPI and PostgreSQL—built to scale, easy to integrate, and fully documented. Whether you’re launching an MVP, building a microservice, or replacing legacy code, I provide fast, well-structured backend systems that are cloud-ready and easy to maintain.
What sets this project apart is my ability to move quickly without sacrificing quality. With a background in AI, healthcare tech, and secure systems development, I’ve built APIs for startups, federal research teams, and enterprise platforms. I don’t just write endpoints—I deliver modular, extensible code with clear authentication, error handling, and database logic that works out of the box.
Clients appreciate my clarity, speed, and the fact that I write code that others can pick up without a 30-minute walkthrough. If you need something built fast—and built right—this project is for you.

Emergency: Finish “Bad Portrait” Tool (Continue Existing Backend OR Build Fast Sketch Version)
Lucas jumped into this project and did such a diligent job -- he's a problem-solver and was very much invested in seeing it through and in constant communication. Amazing relief coming off other freelancers who were in comparison low-transparency and not correctly following the brief.
