About

Highlights

Engagements

• Scaling AI Risk Governance & Review Marketplace Automation at YouTube

  • 3x safely product launches
  • 600k+ daily reviews automated
  • 68% precision lift in review ranking

  Problem

  Fragmented safety reviews and manual routing created multi-week launch bottlenecks as YouTube rapidly expanded into GenAI, commerce, and social features.

  What they did

  Founded and led the Cross-Product Safety (XPS) org as Group Product Manager, establishing modular safety packages, scoping-phase risk criteria, and mitigation frameworks across all YouTube surfaces. Built and led a team of 4 PMs across Policy, Eng, and Ops. Spearheaded the architectural overhaul and automated ranking layer for a 600,000-review-per-day human-in-the-loop safety marketplace.

  Result

  Slashed median risk-to-mitigation turnaround from weeks to days, drove a 3x increase in safely managed product launches, and automated routing for 600K+ daily safety reviews.

• Unifying Siloed Chatbots into an Agentic AI Platform (Ask Advisor)

  • 4 siloed agents unified into 1 assistant
  • 153 engineers across a 5-PM org

  Problem

  Advertisers faced separate chat agents in Google Ads, Analytics, Merchant Center and Support, with no shared context and no clear owner for the experience.

  What they did

  Defined the core platform strategy and agentic UX workflows to unify siloed conversational agents across Ads, Merchant Center, Support, and Google Analytics. Drove cross-org alignment up to VP-level approval for a single unified architecture, and co-designed the shared-memory context layer allowing persistent state as users move across product surfaces.

  Result

  Won VP approval and shipped Ask Advisor globally in English, merging 4 agents into one shared-memory assistant, with a major drop in advertiser support contacts. Led 5 PMs and 153 engineers.

• Accelerating Release Velocity & P&L Growth for AWS Elastic Transcoder

  • 7x increase in public release velocity
  • 7 public features shipped in 6 months
  • 1 new service MVP funded

  Problem

  A nascent cloud media service had shipped only 1 release since launch and needed rapid enterprise feature velocity, pricing optimization, and P&L scale.

  What they did

  Stepped in as sole Product Manager owning end-to-end roadmap, P&L, pricing strategy, and customer GTM for AWS Elastic Transcoder. Restructured engineering prioritization and customer discovery loops to unblock enterprise adoption across media and developer ecosystems.

  Result

  Accelerated product velocity from 1 to 7 public releases in just 6 months, expanding enterprise media adoption while managing full service P&L and pricing architecture.
