About Me

I'm a full-stack engineer with nearly a decade of building and scaling software. I led frontend engineering at HealthifyMe as it grew past 35M users, then co-founded and was CTO of CarbonSync, a GenAI eco-design startup. Today I'm hands-on building GenAI in production.

I write about how software actually gets built and scaled. Based in Bengaluru, India.
