Hey, I’m Piotr Radosz — most people online know me as Piotron. Somewhere between “it’s fine” and “we should probably fix that.”

I’m a Staff DevOps Engineer based in Gdansk, Poland, with over 12 years of keeping infrastructure alive and, more importantly, keeping it from falling over in the first place.

What I do

I run Undefined Network — a consultancy I started in 2017 to help companies design infrastructure they can actually sleep through. Through it, I’ve worked with clients across Europe and the US — from pharmaceutical companies and automotive manufacturers to fintech startups and big data platforms. The common thread: systems that need to be up, fast, and secure, in environments where “it works on my machine” isn’t an acceptable answer.

My toolbox these days leans heavily on Kubernetes, Terraform, AWS/GCP, and GitOps workflows with FluxCD and Argo CD. But I’ve spent enough years wrestling with bare metal, Proxmox clusters, and late-night PostgreSQL query optimization to never take managed services for granted.

When I’m not working

I’m probably doing one of these:

  • Designing something in CAD that I’ll spend hours 3D printing
  • Reading sci-fi (or watching it)
  • Playing board games or video games
  • Listening to vinyl — preferably while doing any of the above

This blog

I’ve been writing here on and off since 2012. You’ll find posts about infrastructure, DevOps, tech opinions, and whatever else I’m tinkering with. The older Polish posts are archived under Polish Post Archive if you’re curious about my earlier writing.
