Description

Senior Product Designer with over 10 years of experience, I operate at the intersection of brand identity, interaction, and product innovation. My approach is to translate technical subjects and business constraints into clear and simple user experiences.

As a pivot between management, product, and engineering, I ensure strategic alignment from initial scoping to technical delivery. I work with major corporations (Renault, L'Oréal, Orange) as well as scaling startups (Fintech, Musictech).

Brand × product:product identity, visual territory, guidelines, brand-product coherence

Structuring:workflows, information architecture, states/edge cases, data and dashboards

Production:design system (tokens/components), specs & handoff, design QA, collaboration rituals with tech teams

Création d'un prototype et de l'identité visuelle de la plateforme Caryon - Caryon

Reviewed on 2/27/2026

I worked with Romain on the creation of the prototype and the visual identity for the Caryon platform, a B2B SaaS solution in regulatory compliance for medical devices. Romain delivered excellent quality work within the given timeframe. He is very conscientious, diligent, and structured in his approach. He knows perfectly how to start from a blank page and transform a complex strategic vision into a clear, coherent, and impactful user experience. His listening ability is a real asset: he takes the time to understand the business, technical, and product challenges before proposing relevant solutions. Communication was always fluid, proactive, and professional throughout the project. I recommend Romain without hesitation for any UX/UI project requiring strategic thinking, rigor, and attention to detail.
