API and Backend Development

A good backend is invisible: it stays fast, it does not lose data, and the frontend team never has to guess how an endpoint behaves. I build APIs and the services behind them with clear structure, validation and documentation.

I work with Node.js (Express and NestJS) and Laravel, on PostgreSQL and MySQL, and I regularly connect products to payment, messaging and CRM providers through their APIs and webhooks.
