About
I understand things by making them.
I lead engineering at Studio, where I build the AI behind personalized coaching apps. Before that I co-founded a design marketplace and was the first hire at a YC company. I've shipped embedded Rust and iOS apps.
The material changes, code or yarn or dough or seeds, but the habit is the same: learn the basics properly, then make something you'd actually use.
