Mårtensson
I design digital products that have to work in real life — national rail, postal infrastructure, and sleep tracking used daily by millions.
Teams usually bring me in when a product has grown complex and decisions start conflicting. If that sounds familiar, email me →

About
I design products people rely on in everyday life — travel, logistics, and health. I work long-term inside teams, shaping structure, flows, and clarity across product and engineering.
My background in photography, architecture, and communication (Berghs School of Communication) informs a calm, reliable approach to complex systems. I’m usually brought in when a product has grown beyond individual screens and needs structure across the whole experience.

Most of my work lives inside products people use every day. This site only shows a small part of it.
If you’re working on something complex and long-lived — I’d be happy to talk.
