Engineering at enterprise scale

I'm a Senior Full Stack Developer and Technical Consultant at EY with over 8 years of experience building production-grade applications across the full stack. My work sits at the intersection of frontend craft and backend architecture.

I specialize in React.js, Next.js, NestJS, TypeScript, and GraphQL — building systems that are performant, maintainable, and designed to scale. I've worked across fintech, HR-tech, and enterprise consulting.

Currently based in Bengaluru, open to international opportunities across the USA, Canada, UK, Australia, and Germany.
