(04) About
Hi, I'm Robin.
I'm a UI/UX designer from Marne on Germany's North Sea coast. For more than three years I've been designing mobile apps – for an energy utility's field technicians, for clinicians at a medtech startup and for a leisure community.
My projects have one thing in common: a lot of complexity – lots of data, fixed procedures, expert users. My aim is user-centred design with intuitive interaction, visual clarity and consistent interfaces.
Because I know how designs get built – now also hands-on in Flutter – my work isn't just good-looking, it's buildable.
