I was working in a Windows-centric environment and started using ProxMox as the hypervisor instead of Windows Server. This combined with my self. Hosting hobby (Proxmox mini PC cluster, network diagrams of vlans, self hosting my own blog website, having a handful of small tools in my git repos) was what sold my current company on hiring me, more than my resume of working in tech.
