I care about interfaces that feel clear, fast and reliable when the product gets complex.

About me

I'm Guillaume.

I'm a frontend developer from France, focused on Web3 and fintech products: trading market screens, dashboards, wallet flows & API-connected interfaces.

Before code, I worked as a leather artisan at Hermes.
42 Lyon gave me the engineering base; craft gave me patience, precision and a high bar for finished work.
