Co-founder, FinMoon AI · Hyderabad, India

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.

How I lead

Engineering decisions are business decisions.

The principles I bring to every team, product and architecture review.

  1. 01

    Architecture before AI

    Understand the constraints — cost, latency, trust, failure modes — before choosing a model. AI is a component, not an architecture.

  2. 02

    Cost is a feature

    Every architectural decision is also a financial one. I design with the cloud bill open in another tab.

  3. 03

    Ship the MVP, earn the scale

    Build the smallest thing that proves the problem is real, with seams in the right places so it can grow without a rewrite.

  4. 04

    Platforms are products

    Internal platforms have users too. If developers route around your pipeline, the pipeline is wrong.

Experience

Every layer of the stack, every seat at the table.

Developer, DevOps lead, principal engineer, founder. Each role widened the blast radius of my decisions.

About

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 — in terms of risk, cost, 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.
