About Mathieu

Fort de 17 années d'expérience, je suis un développeur Front-End passionné, maîtrisant les technologies web les plus récentes comme TypeScript, Web3, Web Components, React, Svelte, Vue et Node/Bun/Deno.

J'ai eu l'opportunité de contribuer à des projets d'envergure chez Consensys ainsi que dans des entreprises renommées telles que WeTransfer, Reddit, Microsoft, Rolex et Pandacraft. Ma grande capacité d'adaptation et d'apprentissage me permet de relever rapidement de nouveaux défis, tout en aidant les entreprises à surmonter leurs obstacles et concrétiser leurs ambitions.

Je me distingue particulièrement dans le développement et la maintenance de fonctionnalités essentielles, l'amélioration du confort de travail des développeurs, et l'optimisation des performances web. En tant que mentor, j'accorde une grande importance à l'accompagnement des développeurs juniors, au partage des connaissances, et à la création d'une ambiance de travail à la fois stimulante et conviviale, favorisant une communication ouverte et bienveillante.
