Summary
🤩
Rockstar🎓
Top SchoolMariusz Mazur is a Principal SRE with 24 years of hands-on experience building and operating resilient cloud and virtualization platforms, currently focused on OpenShift at Red Hat. He combines deep systems-level coding (x86 asm, C, Python) with long-running operational ownership—having run hosting, PKI, VoIP, and datacenter migrations end-to-end—so he balances reducing technical debt with shipping working products. A pragmatic DevOps engineer who has contributed Kubernetes modules to the widely used Ansible project, he routinely uses Ansible, OpenStack, KVM/libvirt and Debian/Ubuntu in production. Mariusz works remotely without churn, favors sustainable pace over burnout, and writes concise documentation to tame unfamiliar systems. Fluent in English and Polish, he brings low-ego reliability and a track record of solving awkward infrastructure problems like tape-loader driver workarounds and complex high-availability designs.
