About

I’m an engineering leader focused on building high-performance database and distributed systems. As Co-founder and former CTO of PeerDB (YC S23) — acquired by ClickHouse — I helped shape a new approach to Postgres replication, making real-time analytics simple and accessible. At ClickHouse, I now lead engineering for database integrations and foundational systems that power the company’s next generation of data infrastructure. Earlier in my career, I contributed to large-scale systems at Google (Flutter, Fuchsia), Palantir, and SafeGraph, working on everything from rendering engines to geospatial platforms. I care deeply about building systems that are fast, reliable, and elegant — and about growing strong technical teams grounded in openness and curiosity. I’ve long enjoyed contributing to open source, and in a past life, was deeply into competitive programming, representing India at the ACM ICPC World Finals.
