Engineering

Backend, data infrastructure,
and the product problems in between.

I build software across the product and infrastructure layers. For more than seven years, I’ve built products, led platform initiatives, and owned critical backend and data systems from architecture through adoption and scale.

At Udaan, I owned SQL infrastructure across reliability, observability, cost, and developer enablement, helping reduce database costs by 75%. I also helped build Percept Insight from its early days, working across Druid infrastructure, query systems, and AI-assisted analytics; created snorql, Udaan’s first open-source project; and co-founded SIGDB, an organisation-wide database community.

Earlier, as a founding engineer at Clarisights, I built across the product and platform layers of a high-scale marketing analytics system.
