I started as a designer. Then I kept shipping — and never really stopped.
Fifteen years in, my job sits where design, product and engineering meet. I co-founded three companies — a roommates' network acquired by Nexity, a community platform acquired by Haiilo — before joining Hugging Face in 2021.
Today I run product there: the model hub, Spaces, inference, and the small interface decisions that let millions of people touch open AI. My rule is simple — shipping is the most important thing.

Best reached on X or LinkedIn. If it's about a Space, an agent, or a design that needs shipping — that's my favourite kind of message.
