Over deze dienst

Need a backend for your web or mobile app? I will build a clean, well-structured REST API with Node.js, Express and PostgreSQL that is easy for your team to extend.


I build Node.js and PostgreSQL services in production, including billing APIs and feature flag systems for a SaaS product.


What you get:

  • REST endpoints with input validation and clear error messages
  • PostgreSQL schema with migrations
  • JWT authentication (Standard and Premium)
  • Jest tests for the main flows
  • A README with setup steps and example requests

Have an existing API that needs new endpoints or fixes? Message me for a custom offer.
