Rockstar🎓
Top SchoolMarek Libra is a Principal Software Engineer based in Brno with over 20 years across hands-on development, pre-sales and management, currently shaping UX and front-end experiences for Red Hat’s hybrid-cloud projects like OpenShift and KubeVirt. He blends deep JavaScript/React and Java expertise with systems-level experience in Linux, Kubernetes, virtualization (KVM/libvirt) and operator-based deployments, often contributing via Ansible and Go for cloud-native workflows. A steady open-source contributor, Marek has enhanced high-profile projects such as the OpenShift Console, Backstage and PatternFly—adding UI components, notifications UX and console integrations that improve developer and admin tooling.

Fluent in English with working German and learning Spanish, he pairs strong social skills with a pragmatic focus on shipping reliable, user-centered cloud software. An understated strength is his cross-domain fluency—from low-level C/C++ and virtualization internals to modern React front-ends—making him a bridge between platform and product teams.
