UX Architect since 2007

Every day, I help clients with their digital products’ strategy, research, concept and interactions, as part of the :ratio team.

Clients trust me:

Crafting a new set of tools for designers

The landscape of digital tools for interaction designers is so limited. I decided to do something about it and bringing those missing tools to life.

The first tool is Gimbalst, to prototype your information architecture and navigation.


I enjoy sharing my experience and reflections, for example about hypothesis-driven design, or designing for the unconscious.

I often speak:
FRED 2013 • Flupa UX Days 2015 • Flupa Lyon 2016 • Swiss Tech Talk 2016 • Blend Web Mix 2016 • UX romandie 2017

Organizing conferences, building communities

I organize international conferences and local meetups, with a strong focus on spreading the importance of Interaction Design in Europe.

It happens quite often too:
Interaction 18 • UX Lausanne 2014 – 2017 • Interaction 14
IxDA Europe • UX romandie • IxDA Lyon.


I teach User Experience Design to master students, share my own experience as a practitioner, and jury student projects.
