About this gig

Your app needs a back-end that won't fall over the first time two people use it at once.


I build REST APIs in Node.js (Express, NestJS) or Python (FastAPI, Django) with PostgreSQL, MySQL or MongoDB behind them. Authentication, roles, validation, error handling, and documentation that someone else can actually follow.


What you get:

- Clean endpoints with proper HTTP status codes

- A database schema designed before a line is written, not improvised

- JWT authentication and role-based permissions where you need them

- Input validation and sensible error messages

- A Postman collection so your front-end developer can start immediately

- README with setup and environment variables


I also connect to what you already use: Stripe, SendGrid, Twilio, OpenAI, Google APIs, or any documented third-party service.


Deployment to Railway, Render, Fly.io or your own VPS available on the Premium package.


Send me what your app has to do I'll come back with the endpoint list and a fixed price before you order.

I'm a full-stack developer based in Switzerland. I've built a hosting-comparison platform end to end, a site-management app for a construction company (Windows + iOS/Android + synced database), and spent nearly two years as the IT manager of a startup. Web apps, mobile apps, desktop software, APIs, databases - and fixing code someone else left behind. JavaScript, TypeScript, React, Node, Python, Java, PHP. I work remotely on European hours. I ask questions before I start, I quote a fixed price, and I hand over source code you can give to any other developer. French, English, German.
