About this gig

Hi, I'm a full-stack developer with 5+ years of experience building production-grade backends with Node.js, Express, and MongoDB. I've designed and shipped APIs powering fintech, healthcare, and social platforms.


WHAT I BUILD:

REST APIs with Node.js + Express

MongoDB / PostgreSQL / MySQL database design

Authentication (JWT, OAuth, refresh tokens, role-based access)

Payment integration (Stripe, Razorpay, PayPal)

File uploads and storage (AWS S3, Cloudinary)

Third-party API integration (Twilio, SendGrid, Firebase)

Real-time features with WebSockets / Socket.io

API documentation (Swagger / Postman)

Cloud deployment (AWS, Heroku, Railway, Render)


WHY ME:

5+ years writing production Node.js code daily

Clean, well-structured, scalable code

Proper error handling and validation

Security best practices (rate limiting, sanitization, CORS)

Source code with clear comments


HOW IT WORKS:

1. Share your API requirements or existing schema

2. I'll send a clear scope, endpoints list, and timeline

3. Daily progress updates

4. Test the API with Postman before delivery


Most client work is under NDA, but I can share demo projects on request.
