Tomasz Gradek · DevOps & Infrastructure Engineer
I’m a DevOps engineer, and these days that mostly means real servers in real racks. Linux, Windows, Proxmox, the network that ties them together, and enough monitoring to know when something is off. Cloud too, when it actually makes sense.
Linux and Windows servers built the same way every time, so rebuilding one is boring instead of scary.
If I’ve done something twice by hand, it ends up in Ansible or a pipeline, usually with a check that stops the third attempt from going wrong.
Alerts that say what’s actually wrong, and backups I’ve restored at least once. An untested backup is just a hope.
Office networks, VPNs and tunnels between sites, plus security reviews that end in a short, sorted to-do list rather than a scary PDF.
A few things I can talk about publicly. The details are simplified on purpose.

My own servers, all managed with Ansible and set up so that one typo can only ever break one machine.

Deployment and CI/CD
One repository describes every game server the community runs. CI catches the mistakes that used to reach players, and rolling back is just a commit.

I went through another community’s forum and account services looking for holes, fixed the worst ones and got their test suite passing again.

Why asking a Redis-compatible node for its role isn't enough after a failover, and how one HAProxy health check can ask Sentinel and the node at the same time.
A single-threaded server kept freezing and the application looked guilty. Counting page faults per frame pointed somewhere else entirely.
I’ve worked in infrastructure since 2022, but I’ve been breaking and fixing servers for much longer. It started with game servers back in 2009. I live in Poland and work remotely, in English or Polish.
