About

Frontend Developer with 2+ years of experience building production-grade web applications used by thousands of real users — including a government job portal for the state of Telangana and a B2B recruitment SaaS. I specialise in React.js and Next.js, and I've since expanded into full-stack delivery, solo-building and shipping a complete Next.js/Express platform for a freelance client. I care deeply about clean architecture, security, and shipping things that work — and I own what I build, from the first commit to production release.
