Things I've built

I like working on complex systems, building fun products and getting my hands dirty with code. Here's some of my recent work.

Muse Spark

Meta's frontier model. I work on building the supervised fine tuning (SFT) pipelines and benchmarking systems behind it.

Business AI

I worked on Meta's Business AI agents and outcome measurement, allowing for general availability.

Marketing Messages

Commerce Insights

One consistent view of commerce across many stores, built on HLL sketches, query tuning and re-modeled views that cut months off development.

A graph data-model redesign and Spark tuning for measurement pipelines at ads scale. Compute down 95%, storage down 96%.

Off the clock

When I'm not at a keyboard I'm usually somewhere with no signal: hiking PNW trails, camping by alpine lakes, paddle boarding on glassy water, and shooting most of it on film.

Evenings go to a lot of Balatro and one more game of Age of Empires II. Wololo.

Working on something fun and challenging? I'd love to hear about it.
