About this gig

Need a backend API for your application? I'll build a clean, working FastAPI backend or wire an existing API into your Python project.


What I can build or integrate:

  • REST API backends with FastAPI
  • API integrations (third-party services, webhooks, OAuth)
  • CRUD endpoints connected to PostgreSQL
  • Data pipelines exposed via API
  • Backend logic for existing frontends


What you get:

  •  Clean, structured Python code
  •  Proper error handling and status codes
  •  Endpoints that match your frontend's expectations
  •  Source code always included


My background:

MSc Computer Science (University of Twente). I've built REST APIs with FastAPI and PostgreSQL from scratch, including a recommendation engine API with tag-overlap scoring. Comfortable reading existing codebases and integrating without breaking what already works.


To get started, send me:

  1. What your API needs to do
  2. Any existing code or frontend I need to connect to
  3. Your preferred database (if any)


Note: Not sure if your project fits a package? Message me first I'd rather scope it correctly than overpromise.

MSc Computer Science graduate (University of Twente) specializing in Python backend development, automation, and API integration. I build clean, practical solutions — scripts that work, APIs that don't break, and backends that do exactly what they should. Experienced with FastAPI, PostgreSQL, REST APIs, web scraping, and debugging. My thesis involved designing and evaluating four AI algorithms for a commercial game in C#/Unity, so I'm equally comfortable at the algorithmic level. I keep things simple, communicate clearly, and deliver on time.
