Hi, I'm Kai Magnus Müller,

a product designer and developer who specializes in complex systems and tools for experts. At Sopea I drive design, strategy and growth for a suite of HR products and use my coding skills to develop prototypes and collaborate with developers.

I also teach Interaction Design at HfG Schwäbisch Gmünd and led design for insurance and investment applications and design systems at Allianz.

Highlights

EPIC: What I Learned While Designing For Power Users June 2024 Redesign, UX Research, Expert User Interfaces
Build and Update Icon Libraries With ILM May 2024 Tutorial, Icons, Figma Plugin

Whenever I get that creative itch, I develop small hobby projects, like Tree Navigator and Icon Library Manager for Figma, or Collections, an experimental platform for knowledge management to explore how computers can help us think and create.

While studying, I wrote a bachelor thesis about building wayfinding systems, designed a browser built for research (which inspired Collections), and went to Japan.

I also prototyped an interactive exhibit during my time as a student, and we later developed an extended version for the exhibition 100 Prozent Baumwolle at Übersee-Museum Bremen.
