Summary
🤩
Rockstar🎓
Top SchoolJán Stanček is a Principal Software Engineer based in Brno with 15 years of experience specializing in Linux kernel maintenance, test automation, and backend systems reliability. At Red Hat he has progressed from kernel generalist and team lead for Kernel General Test to Y/Z kernel maintainer, driving infrastructure, triage, and developer support for kernel smoke testing. He is an active open-source contributor to critical projects such as the Linux Test Project and Autotest, where his work prevented race conditions, improved error handling for system calls and NUMA scenarios, and hardened test harnesses against unexpected reboots. Comfortable in C/C++ and low-level Linux development since embedded telecom work, he blends hands-on debugging with leadership in quality engineering. Colleagues rely on him for pragmatic fixes that surface from deep understanding of kernel internals and test orchestration.
