Hello, I am a French self-taught frontend engineer and UX/UI designer.
I built my first website in 1998 on Multimania: a Game of the Goose
written in JavaScript 1.2, with the same HTML as this page. I have
been doing it professionally for more than 20 years, since I started
my own web agency in May 2005.
At Genedata, I am the senior of the team: I own the frontend
architecture and the technical choices, design the user interfaces,
and set up AI for the team. In 2025, I also founded Randuro, a
mobile app for enduro riders that I build and run almost entirely
with AI.
Before 2011, I focused on PHP, SQL and software development. In
2009, the book «Ergonomie Web» by Amélie Boucher (Ergolab) changed the way I saw
my work, and since then I have focused on front-end technologies
and user interface design. I love simplicity, lightness, performance
and speed, as well as web standards and accessibility. And I am
endlessly curious about new web technologies.
My first lines of code were written in BASIC when I was 8, around 1990.
It took me the whole drive across France, on the first day of the
holidays, to get my program to ask my parents their names, ages and
more.
Timeless!
