I build clean, maintainable backend systems and REST APIs using Python and FastAPI.
I can help with API architecture, authentication, PostgreSQL/database integration, third-party APIs, business logic, background processing, validation, testing, Dockerization, debugging, and deployment.
I can work on both greenfield applications and existing Python codebases, including fixing API issues, adding new endpoints, integrating external services, and preparing applications for production deployment.
For larger systems, I prefer milestone-based delivery beginning with the backend architecture and data model.
