In short

Technology leader who takes products from first commit to production scale.

A decade across the full stack of building software: writing it, shipping it, running it, and leading the teams that do all three. Today I co-lead FinMoon AI, an AI decision assistant for personal finance in India. My engineering home before that was Zemoso Technologies, where I grew to Principal Software Engineer III.

I’m a millennial who thinks like a Gen Z hacker in a lab — always asking why, how, and what if.

My path went developer → senior developer → lead DevOps engineer → principal engineer → founder. Each step widened the blast radius of my decisions: from a function, to a service, to a platform, to a company. That path is why I think about technology the way an owner does. I weigh risk, cost and speed, and the people who have to live with the system after it ships.

Outside work I run a home lab: a Raspberry Pi Kubernetes cluster, a ZFS-backed NAS, a self-hosted photo platform, and agentic automations that switch real circuit breakers. It’s where I test ideas before I bet a team on them.
