Service

Python backend and API development

FastAPI and Flask backends, from the first endpoint to production.

What's included

  • REST API design and implementation with FastAPI or Flask
  • Background jobs and queues with Celery and RabbitMQ
  • PostgreSQL schemas and queries
  • Auth with JWT, signed URLs and token-based launch flows
  • Docker, Nginx and deployment to AWS or GCP

I build backends that stay fast under load. For 4baseCare, I built a FastAPI service that serves gigapixel images as pre-generated tiles near 30 ms under load, down from more than 3 seconds per tile on demand.

How a project runs

We agree on the scope and the API shape first. I build in small steps you can review, with tests from the start, and I hand over docs and a deployment you can run without me.

Questions

Can you work with my existing codebase?

Yes. Most backend work starts inside a codebase that already exists. I read it first, then change it in small, reviewed steps.

Do you write tests?

Yes. Tests are part of the scope we agree on at the start.

How do we start?

Send a short description of what you need. I reply with questions, then a scope and a timeline.
