The host everything else runs on. Proxmox VE, running the VMs and containers behind every other project here — snapshotted and backed up so I can break things safely.
I wanted real hardware I could break and rebuild, not a cloud sandbox that resets when the free tier runs out. So I built my own. The host now runs everything from a Jellyfin container to an OPNsense firewall VM.
It's the base layer for every other project here. That also makes it where I learned the operations discipline: snapshot before risky changes, schedule backups, rebuild broken services instead of guessing at fixes.
The habits mattered more than the technology. Snapshot before you change something. Back up before you trust it. Rebuild from a known-good state instead of troubleshooting blind — discipline that's invisible until the day it saves you.
