Summary

Creative technology generalist with about 30 years of experience as a freelance software developer. Originally coming from the games industry in 3D graphics/animation, I now work primarily as a software engineer/solution architect. Broad technical overview, fast onboarding, strong interdisciplinary skills, user-centered and solution-oriented perspective.

Over my long time as a freelancer, I've developed a high level of flexibility, self-organization, responsiveness and initiative. Although I'm used to working remotely, I'm a team player – often across borders. I have a talent for explaining technical topics in non-technical language.
