Summary
🤩
RockstarMario Kleiner is a seasoned systems and software architect with 23 years of experience, currently working as Dipl. Inf. at the Max Planck Institute for Biological Cybernetics in the Stuttgart region. He specializes in low-level Linux kernel work—particularly display and graphics subsystems—where his contributions improve stability, vblank/page-flip handling, and hardware-specific behavior even on unconventional platforms like Apple hardware. Beyond kernel engineering, he maintains and extends scientific tooling such as Psychtoolbox-3, adding precision measurement and sound/visual test features that reflect a strong experimental-computational mindset. Comfortable bridging research and production, he combines rigorous debugging and refactoring skills with a pragmatic focus on performance and accuracy. Colleagues can expect a developer who thrives on solving subtle, hardware-adjacent problems that most higher-level engineers never see.
