I build production systems on Linux. And I keep them running myself.

Linux administrator from Poznań, working in IT since 2022 – most recently about 1000 workstations across two sites. In my own time I built a production Kubernetes environment that serves sites with real users. Looking for work as a Linux / DevOps / Platform Engineer – remote or on site in Poznań.

How I work and what I look for

  • I start a collaboration by clearly agreeing the scope and terms.
  • I say plainly what works and what does not – my own mistakes included. Example: Cilium
  • I work best where infrastructure and quality come first.
  • I am looking for a team where I can keep growing, not just fight fires.
