About me

I build interfaces for the web, from the design file to the last frame of animation. More than 15 years of it, most recently for On and Luca Faloni. I care about motion, accessibility and pages that load fast.

Selected projects

They say a picture is worth a thousand words; then videos must be worth millions. Here are a few I'm proud of.

A digital hub that promotes On's athletes, their stories and events related to the Paris 2024 Olympics.

Introduced Storybook for component documentation and developer onboarding. It improved the adoption of the Figma design system and ensured design consistency across On's digital products.
