About me
I'm a Linux systems administrator on Česká spořitelna's Siebel CRM platform — a system I've worked on in several roles since 2017: support, administration, development, and now production operations.
Day to day that means deploying releases to OpenShift, building pipelines in Jenkins, automating configuration with Ansible, and keeping production healthy through Grafana monitoring and on-call incident response. A development background in Angular, TypeScript, Python and Go means I write my own tooling rather than waiting on someone else to — and I'm looking to take that further, into a dedicated DevOps / Site Reliability role.
What I do
-
Releases on OpenShift
Rolling out and rolling back releases across test and production, managing pods and deployments.
-
CI/CD pipelines
Jenkins and GitLab CI pipelines that make releases repeatable, faster and less nerve-wracking.
-
Automation
Server configuration and recurring ops tasks codified in Ansible instead of runbooks.
-
Monitoring & incidents
Grafana dashboards, daily log analysis and on-call response — catching problems before users do.
-
Linux administration
Running production and test Linux environments behind a core banking CRM platform.
-
Own tooling
Years of Angular, TypeScript, Python and Go — so when ops needs a tool, I build it.
