Compiling code that compounds capital | CTO at Zerodha Fund House

About

I’ve spent the last 12+ years building technology for the Indian capital markets — from brokerage integrations at smallcase to now leading engineering as CTO at Zerodha Fundhouse. My work has always sat at the intersection of finance, technology, and scale. At smallcase, I built out core infrastructure and brokerage systems that powered millions of investors. Today at Zerodha Fundhouse, I’m focused on creating a modern, cloud-native mutual fund platform — with reliability, compliance, and simplicity at its core. Beyond the tech, I care deeply about engineering culture and org design. I’m building frameworks to spot dysfunction early, realign power structures, and set up engineering teams for scale and autonomy. What I’m good at: Building fintech products with regulatory + reliability focus Designing engineering orgs for alignment and autonomy Bridging business and tech in high-stakes environments Always open to conversations on fintech, infra, org design, or content collaboration.
