About

I build and lead the teams and platforms that turn messy, large-scale data into production ML businesses can actually use. Over 6+ years across BFSI, FMCG, and Media & Entertainment, I've moved from building models to architecting full ML ecosystems and leading the cross-functional teams that ship them. Today I lead a 12+ person function at bluCognition, owning the technical roadmap, cloud architecture, and delivery for a client-facing, multi-tenant ML platform that lets enterprise clients match portfolios against tens of millions of records and train their own credit-risk models — without engineering hand-holding. What I care about: entity resolution at scale pragmatic, low-maintenance architecture with cost as a first-class constraint; applied Generative AI on real problems, not demos; and growing people through hiring and mentoring.
