Hi, I'm Joffrey. But people also call me «Tonton». I am a Graphic Designer working in the fields of Strategy, Creative Direction, Design Systems and Interfaces (UX/UI).
I have been working for ambitious companies and start-ups for about 10 years now. Feel free to catch up !

I am currently working on…


After 10 years running my WordPress agency, I'm starting a new Design project focused on Strategy, Thinking and Design Systems.
Bter is dedicated to companies who want to integrate an advanced Design Mindset to help them grow their business and bring to life a real User-Friendly Culture.
«Bter» is also a strong statement. We stand for regular improvement, at the opposite of never-ending perfection research.

10 years running a web agency has led me to develop my soft skills range, in addition to my initial Design practice. Working with various clients, from the first talks to the follow up of an online project, has given me the opportunity to reinforce my Strategy expertise, but also my empathy and my team-management skills. Growing my company encouraged an evolution of my Design capabilities, from Graphic Design to Creative Direction and Design Sytems.

2011 to 2022


Fantassin is a creative web agency based in Lyon, France. We help our clients to launch their project online with a tailor-made approach, living through two fields:
At first, Fantassin is a WordPress agency. We build custom made WordPress website for companies to help them develop their brand online and the autonomy of their marketing team. Having innovation in our DNA, we achieved the fact of becoming a French reference in the WordPress ecosystem, especially because of our high-level practice of Gutenberg, the new content editor. Also thanks to our creative capacities in mostly technical universe.
Fantassin also has a strong User Experience background. This is why we have been working with some serious start-ups, helping them to refine their product interfaces. With time, this practice has evolved, including Design Systems subjects.

My job at Fantassin, as Founder and Partner, included Company Management, Business Hunting and Management, Human Ressources, Design Lead (Creative Direction, UX, UI, Brand), Agency Communication, and of course every function that a CEO has to assume.

2011 to now

Crafting side projects

For years, I was always in need of understanding my customers problematics. I am also a curious person, and I enjoy understanding the way things work. This is why I launched some side projects., first. Just a blog about cool stuff. s simple as it is. This project made me practice my writing (I love that), and I even sold some sponsored articles !
After this project, I tried to launch a CRM based on a WordPress system. The project never saw the sun, but all the interfaces and interactions were there… and are still up to date !
