Senior UX & Product Designer · Barcelona
Hello,
Marc here.
I figure out why people use things, and what makes them fun.
A neuroscientist turned designer: I go from research and data to hypotheses, explore and prototype the strongest directions, and let experiments decide. At Ubisoft I led onboarding and retention for Rainbow Six Siege and mentored designers; now I’m building Gameloft’s design practice from the ground up. I bring what games know about habits and rewards to every product.
