Pratibha Yadav — Full Stack Developer Portfolio

// who I am

About Me

Full Stack Developer with 3+ years of experience building CRM, HRM, and real-time systems using the MERN stack. I specialize in building systems that handle high-volume transactions without breaking a sweat.

Strong focus on performance, scalability, and secure backend systems. I architect solutions that are production-ready from day one — not as an afterthought.

I use AI tools like GitHub Copilot and Cursor AI to accelerate development velocity, enabling me to ship features 40% faster while maintaining code quality.
