Senior Product Manager

By day: Senior PM for M365 Copilot's AI infrastructure at Microsoft — inference economics, GPU efficiency, metering, and launch readiness. By night: sharpening product judgment the slow way, one teardown at a time. This site is my body of work — what I've done, what I bring, and how I think.

Teardowns

Nothing here yet — I'm doing a second pass on the fundamentals before publishing. Weekly teardowns, written fully in my own words, start soon. Check back.

Now

  • Writing weekly product teardowns as deliberate practice — private for now, published here when they're ready.
  • Brushing up on product-sense fundamentals first (second pass through Shreyas Doshi's Maven cohort).
  • Expecting our first child in January 2027.
  • Based in Everett, WA. Working remotely, in the office when it matters.

About

My work has moved between software engineering, product management, and AI infrastructure. I like problems that sit between technical systems, business models, and the people who use them.
