About this gig

Need a stress-free Node.js developer for a secure backend app?


Skip the headache of broken endpoints and sloppy code. I build scalable, fast REST APIs using Express.js and MongoDB, tailored to your exact business logic.


What I Offer:

  • Custom REST API development (Node/Express)
  • Clean database design & schemas with Mongoose
  • Security: JWT auth & role-based validation
  • Seamless third-party API & gateway integrations
  • Postman API documentation for fast testing
  • Performance optimization & legacy code debugging


Tech Stack:

Node.js, Express.js, MongoDB, Mongoose, JWT, REST API, JavaScript, TypeScript, SQL, Git, Docker, Render, AWS.


Our Process:

  1. Requirements: We map out your app logic.
  2. Architecture: Creating schemas & secure routes.
  3. Testing: Checking every route via Postman.
  4. Handoff: Deploying live with a clear README.


Why Choose Me?

  • Clean, commented code ready for front-end linking.
  • Free Postman file to test your live endpoints.
  • Quick updates throughout the order.
