Since my first portfolio on October 2016, I began building my universe around one thing that kept my attention since I was a child: cities and their energy, using the symbols of light in physics and flash.

Coming soon


Maybe the more visual way to dive into my universe, you may find superabundance of references of color palettes inspired by Piet Mondrian, typography compositions and physics symbols.

About me as a human

“I believe in the process but even more in the connections we build and strenghten along the way between companies, teams and end-users, all as humans.”

My name is Yann-Edern Gillet. I’m a French designer living in Paris, France. My main area of focus today is on systems, digital products and interfaces. DMs are opened!

In my spare time I still spend a lot of time on screens, but more as a front-end engineer. I love learning new things, especially with Vue, Nuxt and GSAP. More recently I’m learning the craft of icon design (yup, the ones you saw earlier are born on my computer). I like the idea of crafting myself every pixel of my creations, both in design and code, like this portfolio.

When my hands are not on my mechanical keyboard, I enjoy taking care of my plants, cook/ try some italian recipes with my girlfriend and building LEGO sets.

To relax, I dive into work of others designers and developers, thanks to Standards Manual, Increment and Offscreen.

I’m also a huge fan of Hip-Hop culture and music. Even if I listen to a lot of US / UK rappers, french rap is deeply anchored in my head + easier to understand as a french person of course. I created playlists for each of my mood, feel free to give it a try!
