SUMMARY
I help startups and businesses build secure, scalable, and production-ready web applications using modern backend and full-stack technologies.

I specialize in Node.js-based backend systems, REST APIs, authentication, and payment integrations, with hands-on experience building real-world MERN stack applications — not demo projects.

My approach focuses on:
- Clean and maintainable architecture
- Secure authentication & authorization
- Scalable database design
- Performance optimization
- Smooth frontend-backend integration

Whether you need to build a backend from scratch, integrate payments, optimize an existing system, or develop a full-stack product, I focus on long-term reliability, not short-term hacks.

What I Can Help You With:
- Backend development with Node.js, Express.js, and TypeScript
- REST API design with proper validation, error handling, and security
- Authentication systems (JWT, Access & Refresh Tokens, Role-Based Access Control)
- Payment gateway integration (Razorpay – test & live environments)
- Database design & optimization (MongoDB, PostgreSQL)
- Redis integration for caching, session handling, and performance improvement
- Full-stack MERN development (React + Node.js)
- API testing and documentation (Postman)
- Debugging, refactoring, and performance optimization
- Git-based version control and clean collaboration workflows
