About this gig

Need a backend API built clean and fast without the fluff?

I've built APIs for rental platforms, e-learning systems, real-time auction engines, and CRM platforms. I know how to structure routes, handle auth, connect databases, and write code that's easy to hand off and maintain.

What I build:

  • REST APIs with full CRUD operations
  • JWT and Auth0 authentication with role-based access control
  • MongoDB and PostgreSQL database integration
  • Third-party integrations Razorpay, Stripe, webhooks, email services
  • Real-time features with Socket.io
  • Serverless APIs on AWS Lambda + DynamoDB
  • Postman documentation for Premium orders

My stack: Node.js · NestJS · Express · TypeScript · MongoDB · PostgreSQL · JWT · Auth0 · Socket.io · AWS Lambda · Razorpay · FastAPI · Python

Message me before ordering describe what your API needs to do and I'll give you a straight answer on scope and timeline.
