Please message me before placing an order so we can discuss your project first.


I build custom MERN web applications, SaaS platforms, CRM systems, dashboards and API-based solutions with a strong focus on backend development.

What I can build:


-Custom MERN web applications

-SaaS and MVP applications

-CRM and admin dashboards

-REST API development

-Firebase & JWT authentication

-Role-based access control

-MongoDB & PostgreSQL integration

-Razorpay payment integration

-Third-party API integrations

-Frontend-backend integration

-CRUD applications

-Bug fixes and new features

-Docker setup and containerization


I can also work with your existing codebase to add features, build APIs, fix backend issues or connect your frontend with an existing backend.


My focus is clean code, proper API integration, reliable data flow and making the complete application work smoothly.

I’m a backend-focused Full Stack Developer with hands on experience building scalable production-ready web applications. I primarily work with the MERN stack and have a strong interest in backend engineering, system design, and clean architecture. On the backend I develop secure and efficient APIs using Node.js, Express and Python frameworks focusing on authentication, database design, performance optimization and maintainable code.
