Summary
🤩
RockstarKay Sievers is a seasoned systems engineer with 26 years of experience building and hardening low-level Linux infrastructure, currently shaping products at Versio Duo from Berlin. Previously a senior engineer at Red Hat and long-time developer at SUSE, he brings deep expertise in device management, kernel-level code, and build systems—evidenced by significant contributions to eudev and kernel projects that improved USB handling, Broadcom support, and partition safety. Known for pragmatic engineering and a taste for "reasonable people doing weird things," he blends meticulous system design with a healthy contrarian streak that keeps tools robust and maintainable. He favors solving hard, under-the-hood problems that others avoid, translating obscure kernel and device quirks into reliable, production-ready behavior.
