Über diesen Service

Need a reliable backend for your app, website or no code frontend? I build clean, secure REST APIs with Node.js, Express, and PostgreSQL or MongoDB.


I'm a full stack engineer with 2 years of professional experience building production backends, including a search system over 290M+ records and an AI document pipeline that cut manual workload by 90%.


What you get:

  • Well-structured endpoints with input validation and proper error handling
  • Secure authentication (JWT) and role-based access
  • Database design and queries optimized for speed
  • Rate limiting, CORS and security best practices
  • Clear documentation (Postman or Swagger) so your frontend team can start right away
  • Optional Redis caching, Docker and deployment


Works for:

SaaS backends, mobile app APIs, dashboards, MVPs, and replacing slow or messy existing APIs.


Before ordering, message me with a short description of your project and I'll confirm the scope and the right package.
