I'm a DevOps engineer and Linux system administrator in Brno. I design, automate and operate infrastructure with Docker, Kubernetes and modern cloud platforms.
The aim is straightforward: a reliable route to production, systems people can understand, and fewer surprises after handover.

I help teams build, ship and operate systems across four connected areas. The tools change; the goal stays the same: reliable production.
CI/CD & Automation
Create a repeatable route from commit to production with pipelines, infrastructure-as-code and GitOps.

How I work
My goal is simple:
make production
predictable.
I want teams to ship changes with confidence and understand the Linux systems they own. That means clear CI/CD automation, useful monitoring, practical security and documentation that survives the handover.
Automate the repeatable
I use CI/CD and infrastructure-as-code to turn deployments into a clear process, not a collection of manual steps.
See problems early
Monitoring, hardening and practical defaults make risk visible before it becomes an outage.
Keep knowledge with the team
I document decisions and ownership so the system remains understandable and maintainable after I hand it over.
