My job: making products clear and teams effective.

For more than 14 years, I have designed digital products for media, banking, cybersecurity and premium advertising, working with large groups, start-ups and SMEs. Alongside this, I have supported brands as a freelancer since 2008: SeLoger, Accor Hotels, leboncoin, Eptimum…

Today I work as Head of Design and Head of Design Ops. I have led cross-functional design teams spread across several countries, and set up design systems and rituals that last.

My belief: a good product comes from a good experience, and a good experience comes from a well-organised team. Hence my favourite areas: design systems, mobile-first, naming aligned with the code to work hand in hand with developers, and AI-augmented prototyping to test earlier and decide better.
