> Product designer. Every product now has two users — humans and agents. I design for both.

This page is a directory of my experiments and a router to my writing. It is not a portfolio.

## What I do

I am a product designer working on what happens to products and design systems when AI agents become users alongside humans: what agents may and may not do, approval gates, autonomy levels, and run-time governance.
