Clusters at work, a rack at home.

An ink drawing of me in glasses and a knit sweater

I’m Robert, an infrastructure engineer. I run HPC clusters at work and a small lab at home, and write down what breaks in both.

Based in Romania, working across the EU

Know the hardware. Automate the rest.

I like understanding systems from the hardware up, then making them reliable and repeatable through automation. Less guesswork, fewer surprises, and things that are easier to maintain.

A drawing of a 2U server taken apart: the chassis with its drive cage, the lid lifted high above it, the fans, the processors under their heatsinks and the memory lifted out, two drives pulled from the front and the power supplies drawn out of the back.

My homelab, where I try things first.

Three Proxmox hosts and a Kubernetes cluster beside my desk. Nothing in it answers the internet, and all of it can be rebuilt from git.

The rack at home, drawn from the front: a Dell R730xd on top; under it, a Synology NAS beside three small Proxmox hosts stacked on a shelf; below, a box of spares, a plant and a UPS.65 W482 mm

Still taking computers apart.

What started as curiosity about a Pentium 4 turned into a career working with infrastructure at scale. The hardware changed. The curiosity didn’t.
