DevOps/Site Reliability Engineer for SLA-Based Systems

I specialize in building, operating, and supporting resilient, SLA-compliant infrastructure platforms with Rancher, OpenShift, and Kubernetes at scale.

About Me

Michal Vasko
Open-source enthusiast and DevOps/Site Reliability Engineer @voidquark

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.
