I will develop nodejs rest api backend with mongodb and express


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.

FAQ
Do you provide source code and database schema?
Yes, full source code, database schema, and API documentation are included. You own everything 100%.
Can you deploy the API for me?
Yes. Cloud deployment is included in the Premium package. For Basic/Standard, it's available as an add-on. I deploy to AWS, Heroku, Railway, or Render.
Will the API work with my existing frontend or mobile app?
Yes. I follow REST standards and provide clear API docs (Swagger/Postman). Your frontend, mobile app, or any client can integrate with the API easily.
Do you handle authentication and security?
Yes. I implement JWT auth, password hashing (bcrypt), input validation, rate limiting, CORS configuration, and protection against common attacks (SQL injection, XSS).
