About
Linux administrator from Poznań. I have been into servers since childhood – I set up my first one in 2013. I have worked in IT since 2022, and in my spare time I run my own production Kubernetes cluster.
The path so far
2013
My first Minecraft server
I was about ten at the time. That server is where it all started.
2016
My own Minecraft server network
With a forum, TeamSpeak and a shop that paid for its upkeep.
2017
The Playergency bot and website
Playergency (formerly eRPe) is a gaming community on Discord, active since 2016. I have been building its bot and website since 2017.
2018–2022
Technical school, IT technician
Vocational exams and the Matura (secondary school leaving exam).
2022–2025
IT for about 150 workstations
User support, maintaining workstations without an Active Directory domain, central antivirus managed from a Linux server. On a small budget I looked for open-source solutions – among other things, I brought an old, unused server back to life with Proxmox.
2025–2026
Administering about 1000 workstations in two locations
A Windows Server domain with Group Policy (GPO), a standard system image for several hundred new devices, a custom intranet on a Linux server.
2026
My own production Kubernetes cluster
From zero to two clusters: GitOps, monitoring, CI and services with real users. PixelArena is a return to my gaming roots, this time built professionally.
Now
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.
- Before I change anything in production I write the plan down, and afterwards I update the documentation.
- I work with AI agents: I delegate, verify and take responsibility for what reaches production. I automate as much as I can without lowering the security bar.
- I use Linux every day (Omarchy today) and run my own server at home on IncusOS, with Home Assistant.
