About Steve
Spécialiste des design systems, en tant qu'ingénieur et leader. Ancien tech lead du DS de Back Market, j'ai géré des design systems en agence, scale up et grande entreprise. J'écris du code accessible et conforme WCAG depuis plus de 5 ans.
Je suis très impliqué dans l'écosystème d'outils autour du DS. Community Advocate et contributeur régulier de Storybook, je gère un collectif de développeurs d'addons Storybook. Je développe aussi un client API Figma et des outils autour des design tokens. Je participe aux travaux du W3C sur la standardisation des design tokens.
Je suis reconnu internationalement dans la communauté DS, avec des participations à Figma Config, The Design System Podcast, The Question et Design Systems France, et des événements co-organisés avec Storybook et Figma.
