About

I build monetization products that scale to billions.

Product leader at PubMatic with a full-stack view of AdTech, spanning sell-side monetization, buy-side platforms, publisher growth, and buyer outcomes.

What I focus on

I build products where marketplace design, infrastructure, and machine learning intersect, especially in systems where milliseconds, signal quality, traffic cost, and buyer outcomes all matter at the same time.
  • SSP monetization & exchange strategy
  • DSP-facing traffic shaping & QPS management
  • CTV, video, mobile app & PMP monetization
  • Supply quality & inventory governance
  • AI/ML-driven optimization
  • OpenRTB, ad-server & marketplace infrastructure
  • Outcome-driven product strategy

I am a curious student of programmatic AdTech: its mechanics, its market dynamics, and the technology that makes it work.

Today

I own core SSP monetization at PubMatic, CTV, video, traffic shaping, traffic quality, DSP QPS, and PMP optimization, products that move billions in programmatic spend.

Before

At Amazon Ads, I built campaign management on the buy side, shaping the trader experience and goal-oriented workflows that took Performance+ from alpha to GA on the Amazon DSP.

Foundation

The rest of my career has been inside PubMatic, scaling the RTB exchange and the OpenRTB API ad server, leading machine-learning-driven optimization, and integrating major DSPs and buyers including DV360, The Trade Desk, Amazon, Viant and Temu.

Industry

I represent PubMatic in IAB supply chain forums, helping shape standards and best practices for how programmatic supply moves across the open internet.

The journey

I joined PubMatic when it was under 150 people. Today it's 1,000+ across 15+ countries, operating globally and powering over $2B in annual ad spend. Helping build that scale, from the inside, has been the defining chapter of my career.

Where it started

I started my career at PubMatic, on the programmatic publisher side. Seeing how publisher revenue actually gets earned, dollar by dollar, still shapes how I build product today.
