What I do
Graphic and Web designer for more than two decades, I now focus my work on UX, and lead the UX design team for different projects or companies.
I have always been passionate about interfaces and interactions, trying to design the best possible experiences with a user-centered mindset and methodology
I started working as a multimedia designer more than 20 years ago, specialising in complex database-driven Flash websites (from the php-MySQL code to the design of the UI), when it was the only available technology to allow for advanced user experiences and dynamic interfaces.
Along with digital and web projects, I developped an extensive “print” experience, creating numerous corporate identities, logos, posters, flyers, brochures and branding identities etc.
I worked for many different clients, SMEs, institutions and multinational companies, such as Swatch, Nestlé, Ville de Lausanne and Medtronic, sometimes as a freelancer, sometimes within a team or as a consultant.
Flexible, independent and at ease working in a team, I have been the UX/UI lead designer for massive projects, from wireframes to Sketch/Figma prototypes.

Please note that most of my UX work is "behind the scenes" and is therefore not really represented here.
