Over deze dienst

I fix backend bugs, including the kind that only show up in production.


Send me the repo and a description of what's breaking. I reproduce it, find the actual root cause, fix it, and tell you what was wrong in plain English. You get a working fix and an explanation, not a patch you can't maintain.


What I work on: Node.js and TypeScript (Express, NestJS, Prisma), Python (FastAPI, Django), PostgreSQL and MongoDB queries, migrations and slow endpoints, auth, JWT and session bugs, broken third-party integrations and webhooks, and Docker and deployment failures on Render, Railway and Vercel.


I've built and shipped production systems: a 3-service trading platform with payments, background jobs and an AI service, and a mini CI/CD runner using Docker, Redis and WebSockets. Live demos on request.


If I can't fix it, you get a full refund. I would rather lose the order than take money for a problem I couldn't solve.


Not sure which package fits? Message me first. I'll tell you honestly, including if your bug is smaller than the Basic tier.

Backend developer. I build the parts of a product that have to work: APIs, authentication, payments, background jobs, and integrations. I've shipped a 3-service trading platform (REST API, PostgreSQL, Razorpay subscriptions, scheduled jobs, and a separate AI service) and a CI/CD runner built on Docker, Redis and WebSockets. Both are live and I can demo them on a call. Mostly Node.js/TypeScript and Python/FastAPI, on PostgreSQL, shipped with Docker. I reply quickly, I tell you when something isn't a good idea, and I don't take work I can't do well.
