About Benjamin

Vous construisez un produit SaaS avec une forte complexité fonctionnelle, et vous avez besoin d'un designer capable d'entrer dans le détail sans perdre de vue l'expérience globale ? C'est ce que je fais depuis 10 ans.

J'aime transformer une complexité réelle en une expérience intuitive. Pas simpliste et jolie, pratique et évidente.

Chez Ledger, j'ai redesigné Vault, la plateforme enterprise de gestion d'actifs numériques pour les institutions les plus exigeantes du secteur. J'ai aussi repensé l'onboarding enterprise de A à Z résultat : une expérience plus fluide pour les utilisateurs et un process scalable pour les équipes internes.
J'ai également conçu Ledger Tradelink, un réseau de trading construit de zéro sur la plateforme de self-custody.


Avant Ledger : les produits cloud de Gandi (VPS, Simple Hosting, WordPress) Komgo (trade finance sur la blockchain Ethereum), des solutions supply chain pour LVMH et du design génératif pour la Commission Européenne.

Encore plus tôt: FranceConnect (authentification publique cross-plateforme) avant son lancement, du motion-design de UI pour Parrot en agence, et un projet étudiant devenu startup pour offrir l'expérience de Jukebox numériques en soirée.

Je travaille tôt dès la discovery (là où les décisions clées se prennent) et en proximité avec les équipes produit, tech et customer success. Le design qui compte est celui qui est livré, adopté, et qui fait bouger les métriques qui comptent pour vous.


Sur quoi j'interviens : audit UX & interview utilisateur · wireframes & architecture de l'information · maquettes haute fidélité · prototypes interactifs · handoff front-end.
Je suis particulièrement à l'aise sur les produits où les enjeux sont élevés, et les contraintes techniques font partie du brief.


Typologies de projets : plateformes SaaS B2B, hardware, outils métiers, onboarding, refonte UX, design 0→1.
