Work
Selected work.
The systems I've built and the companies I built them at, written at the level of detail that belongs on the open web. The personal version of these years lives in the memoir.

Current

Roblox
Content understanding & AI moderation
Models that read ad creative and interactive experiences, feeding signals across the platform — moderation, brand suitability, discovery, ranking, creator and user surfaces — with the evals, human escalation, and auditability that make the decisions defensible. Next up: experience understanding — agents that play experiences to read what static analysis can't see.
Advertising and product systems

Google / YouTube

Google / YouTube
YouTube Flash
Moment-level matching for YouTube advertising using video understanding and brand suitability signals — the early bet that ad placement should be a function of what is happening inside a video. The line of work YouTube later launched publicly as Peak Points at Brandcast 2025 (CNBC, TechCrunch).
