about

Short bio, long footnotes.

I'm a Full-Stack Developer with 3+ years building production systems at scale. Currently Lead Frontend at Atomic Loops — I design React/Next.js architectures, tune hot paths, and ship infrastructure that quietly carries real load. Graduated IIT Kharagpur (B.Tech + M.Tech). My Chrome extensions are used daily by 3000+ engineers.

I'm a Full-Stack Developer with 3+ years of experience building high-performance React applications and the services behind them. I specialize in scalable architecture, performance optimization, and modern TypeScript on both ends of the stack. At Atomic Loops I lead a frontend team, mentor juniors, and own architecture for products that process thousands of records daily. I care about clean abstractions, measurable wins, and code that ages well.
