I build products that scale. Six years shipping at 100M+ users — from search infrastructure that became #2 transaction driver platform-wide, to AI pipelines that cut translation costs by 75%, to SDK platforms that compressed GTM from 10 days to 4 hours.

The path from
engineer to product leader

I started as a Chemical Engineer from IIT Bombay — which meant I learned to think in systems, constraints, and failure modes before I ever wrote a line of code. I pivoted to software engineering, then to product management after completing my MBA from IIM Indore.

At Paytm, I've spent six years building at a scale that most PMs only read about. I've owned the surfaces that 100 million users interact with daily — homepage, search, flyout, profile, SDK platform, localization, accessibility, and the web.

My edge: I think in architecture driven by failure modes. Every layer I've added to a system was added because something broke, not because it looked good on a roadmap. That discipline — from the AI localization pipeline's dual-LLM design to Universal Search's SDK-first approach — is what makes my work hold up at scale.

Currently exploring Senior/Principal PM opportunities in AI products, platform/SDK, and consumer fintech globally. I'm also building AI-native tools as side projects, grounding my PM thinking in what it actually takes to ship.

I'm open to conversations about senior/principal PM roles — particularly in AI products, platform/SDK, and consumer fintech. Preference for fully remote roles globally. Also happy to connect on product thinking, AI pipeline architecture, or anything search-and-discovery related.
