Your infrastructure, run like my own.

I build, monitor and document servers, networks and backups, and I’m selective about the work I take on. What I deliver is built to last; AI helps, but I check every change myself.

The rack at home

Drawn from the front: three small Proxmox hosts, one Kubernetes cluster, and a backup server that is off most of the day. It all comes back from a git repository in about 35 minutes. Take the homelab tour

The rack at home, drawn from the front: a Dell R730xd on top with a printer on it; under it, a Synology NAS beside three small Proxmox hosts stacked on a shelf; below, a UPS, a plant with glasses, and spares: a power supply and disks for the R730xd, SAS disks and a cable tester.65 W482 mm

  1. Spinning Down SAS Disks

    SAS drives ignore ATA standby and the usual tools quietly stop working on them. What actually parks them, and a script that keeps them parked.

  2. Offsite Backup to Oracle Cloud with restic

    An encrypted offsite backup on an Oracle Cloud Always Free instance, no dependencies — in place of a HyperBackup setup that needed a working DSM to restore.

  3. How AI Fed My Anxiety Without Asking

    How AI quietly consumed my focus, patience, and mental space — and what I did about it.
