About this gig

I'm a full-time backend engineer currently building LLM-powered production systems at a tech startup. I specialise in designing and shipping REST APIs that are clean, well-structured, and ready to grow.


What I build:

  • REST APIs with FastAPI (Python) or Node.js / Fastify
  • JWT / OAuth2 authentication and role-based access control
  • Async background jobs and scheduled tasks
  • PostgreSQL, MongoDB, Redis schema design and ORM models
  • Postman / OpenAPI documentation included


Every delivery includes clean, commented code, a working Postman collection, and a brief handover doc so you can extend it yourself.


I don't do cookie-cutter work. I read your requirements properly and ask questions before I start, so you get exactly what you need not a generic boilerplate.


Message me before ordering if you're unsure if I fit your project.
