About Me
Michal Vasko
Open-source enthusiast and DevOps/Site Reliability Engineer @voidquark
Based in the heart of Europe • CET timezone
I'm a hands-on DevOps/Site Reliability Engineer with over a decade of experience supporting mission-critical, SLA-bound platforms in enterprise and hybrid cloud environments.
Currently, I work full-time at cloudWerkstatt, managing infrastructure platforms built on Rancher and OpenShift across VMware and IBM Cloud. I ensure 24/7 uptime, lead upgrades, deploy clusters, automate infrastructure, and support internal tools such as GitLab, Keycloak, Taiga, and more.
I've previously worked for large enterprises such as T-Systems / Deutsche Telekom Solutions, supporting SAP landscapes, and Visma, where I managed private cloud deployments on OpenStack.
When not on-call, I contribute to open-source projects like the Grafana Ansible Collection, build monitoring dashboards, and run a home lab to test new tech.
