Informazioni su questo servizio

Need a reliable backend developer to build your API or integrate AI into your app? You're in the right place.

I specialize in building production-ready backend systems with FastAPI and Python from secure authentication to database design to AI-powered features. I recently built a complete API from scratch covering JWT authentication, PostgreSQL database design, automated testing, and LLM integration, so I bring real hands-on experience, not just theory.

What I offer:

Custom REST API development with FastAPI

JWT-based authentication & authorization (secure, per-user access control)

Database design & migrations (PostgreSQL, SQLAlchemy, Alembic)

LLM integration (Gemini, OpenAI, Claude) with structured, validated outputs

Automated testing (Pytest) & CI/CD setup (GitHub Actions)

Clean, well-documented, and secure code

I pay close attention to detail, write maintainable code, and make sure every project is delivered on time with clear communication throughout.

Why work with me?

  • Real experience building production-style APIs, not just tutorials
  • Security and testing built into every project, not an afterthought
