Projects

A collection of home lab, infrastructure, and automation projects I've built to strengthen my IT skills.

Proxmox Home Lab

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.

Infrastructure as Code & Observability

Rebuilt my Docker host from scratch — provisioned by Terraform, configured by Ansible, monitored by Prometheus, Grafana, and Loki. No more clicking through a UI and hoping I remember what I did.

Microsoft 365 Administration

My day job. Microsoft 365 administration across a rotating set of client tenants — identities, licensing, Exchange Online, and security.

Networking Lab — Phase 1: Segmentation

Segmented a flat home network behind an OPNsense firewall — three VLANs, 802.1Q trunking over a single NIC, per-VLAN DHCP and DNS. Nobody else in the house noticed it happen.

PowerShell Automation

18 PowerShell scripts for network discovery, system health checks, and security auditing. If I do something by hand twice, it becomes a script.
