Relief: Your ride rebuilt as a 3D model
Drop a GPX file and the ride comes back as a 3D model: real terrain, forests, villages, climbs categorised. Everything runs in the browser, the file never leaves your device.
Erwan Guillou
Product Designer
Hi, I’m Erwan. Freelance, and part of 
Vision First.
Designing digital products with teams since 2020, from the first user interview to the last icon. AI made the work wider, and the time it gives back goes to people and the craft.
I’ve designed with the NBA, DAZN and the US Open at 
immersiv.io, and with startups and small businesses.
Not everything I make lives on a screen: there’s more about me.

A public works company with no brand and no website. I built both, then Piquetage, the design system that rules them, then the platform where they write the 44-page memo every tender needs.
