About this gig

I will build backend systems and REST APIs using Node.js, Express, and MongoDB clean code your frontend or app can rely on.

Whether you need a simple CRUD API, user authentication, or a backend connected to third-party services, I build it with proper structure: organized routes, validated inputs, and real error handling.


What you get:

  • REST API built with Node.js + Express
  • MongoDB database with Mongoose schemas
  • Documented endpoints (Postman collection on Standard/Premium)
  • Input validation and error handling
  • JWT authentication (Standard/Premium)
  • Deployment to Render/Railway (Standard/Premium)
  • Source code included, always


Tech Stack: Node.js, Express.js, MongoDB, Mongoose, JWT


To start, share:

  • What your API needs to do (resources/actions, e.g. users, posts, orders)
  • Auth type needed, if any
  • Third-party services to connect (payment, email, etc.) message me first to confirm scope
  • Your existing frontend/app, if any, so responses match what it expects


Not sure which package fits? Message me before ordering I'll tell you honestly what your project needs.
