About

R&D engineer in prototyping and embedded systems

My name is Jean de Bailliencourt, I'm 29. I use creativity and resourcefulness to imagine where technology is heading, at the intersection of three things: what scientific progress makes possible, what people actually want — enthusiasts and general public alike — and a touch of retro design, a style I'm particularly drawn to.

Out of those three come the concepts, prototypes and products you'll find on this site. The most successful ones I take to production.
