Technology has fascinated me since I was a child. Human-centered user interfaces, home automation, machine learning, gaming, connected mobility, digital art, XR, IoT, ... — they all enable me to understand and hack a complex world.
I live and think in projects; and in any of these projects I strive to take on responsibility for achieving and maintaining excellent quality, alone or in a constant exchange with like-minded individuals.
I contribute to purposes that are aligned with my personal values. On a small scale, this means building convenient user experiences; on a larger scale I want to help solve burning issues like climate change and all forms of social inequality.
