About me

Rafi

Full Stack Developer

I build scalable, performant full-stack web applications with a focus on clean architecture and great user experience. Specializing in the MERN stack with Next.js and TypeScript, I've delivered production-grade SaaS products, AI-powered tools, and high-performance client projects across India, the US, and the UK.

When I'm not coding, you'll find me exploring new design trends, contributing to open-source projects, or sharing knowledge with the developer community.
