Over deze dienst

I build Python and Node backends for AI products. 114+ model gateway, 5K

requests per second, 200K records/day.


Your AI feature works in a notebook. Turning it into something users can hit

is a different job: auth, rate limits, queues, retries, cost tracking, and

logs you can actually read when it breaks at 2am.


What you get:


- REST API in FastAPI, Django, or Express

- PostgreSQL schema and migrations

- Background jobs and queue handling

- Auth, rate limiting, and error handling

- Deployed on AWS, or your infrastructure

- Handover doc your next engineer can read


Stack: Python, FastAPI, Django, Node.js, TypeScript, Express, PostgreSQL,

Docker, AWS.


Six years of software engineering. I have shipped an LLM gateway routing 114+

models, APIs sustaining 5,000 requests per second, and AWS pipelines at

200,000 records per day.


Send me what you are building and where it is stuck. I will tell you what it

will actually take.

I build AI agents, RAG systems, web solutions, and automation products that are designed to work beyond the demo, backed by production-grade backend and cloud engineering. With six years of experience in full-stack development and three years focused on AI, I help turn AI ideas into reliable products... from architecture and retrieval pipelines to agent workflows, evaluation, observability, and deployment. Clients hire me when the prototype works but the product doesn't. They keep me as a full stack developer when the AI work needs a real product around it.
