About
Based in Bremen, Germany, I am an engineer focusing on UI/UX design, frontend architecture, web animation, and agentic engineering. I've spent 16+ years building digital products professionally, starting with complex motion design (Flash, ActionScript) and moving into modern web applications and global-scale enterprise systems.
I am particularly interested in "multiplicator" projects: platforms, tools, or architectures that help other people solve complex problems at scale. I prefer interfaces where the structure is clear and the navigation feels natural, especially when dealing with feature-heavy applications.
