About

I build engineering Organizations that scale — and products that last. With 18+ years across Fintech, Payments, Insurance, Media, and Telecom, I've worn many hats: hands-on Java architect, technical lead, and now Engineering Manager leading Nielsen's India GCC with full P&L ownership. What I'm known for: Building teams from scratch — scaled 0 → 20+ engineers in 6 months Delivering at scale — systems handling billions of daily requests at 99.9% uptime Driving business impact — $264K+ annual savings, 40% faster deployments, 60% fewer incidents Bridging tech & business — working closely with Product, Finance, and Regulatory stakeholders My engineering philosophy: great systems are built by great teams. I invest heavily in people — career frameworks, mentoring, and a high-performance culture — because that's what makes everything else possible. Currently leading Backend, FrontEnd teams at Nielsen India. Always open to conversations about engineering leadership, distributed systems, and the future of AI in enterprise.
