Homelab Portfolio
Built, broken, fixed, and learned at home.
A personal infrastructure lab focused on virtualization, networking, self-hosting,
automation, monitoring, media services, and real-world IT problem solving.

Overview
My homelab is a hands-on environment where I design, deploy, and troubleshoot
infrastructure similar to what is used in small business IT environments. It includes
virtualization, firewall routing, VLAN segmentation, Docker services, storage, monitoring,
remote access, DNS filtering, VPN routing, and automation projects.
Proxmox
OPNsense
Docker
Cloudflare
TrueNAS
Grafana
Power BI
n8n
Core Infrastructure
Multi-node Proxmox virtualization cluster
OPNsense firewall/router with VLAN segmentation
UniFi wireless with multiple SSIDs mapped to VLANs
Cisco managed switch for trunking and PoE
TrueNAS storage for shared data and services
Networking
Separate VLANs for home, servers, IoT, and tunnel services
Firewall rules for isolation and controlled access
Pi-hole and Unbound DNS filtering/resolution
Cloudflare Tunnel for secure external access
VPN routing experiments with NordVPN, Mullvad, WireGuard, and Gluetun
Identity & Endpoint Administration
Run a Windows Server domain controller for hands-on Active Directory practice
Manage user accounts, groups, permissions, and domain-joined devices
Use Microsoft Entra ID tenant for cloud identity and Microsoft 365 administration learning
Administer family devices, including kids' Windows PCs, policies, access, and account controls
Practice real-world concepts like least privilege, password management, remote access, and device lifecycle support
Self-Hosted Services
Jellyfin media server with supporting automation tools
Sonarr, Radarr, Prowlarr, qBittorrent, and Gluetun
Nextcloud for private file access
Guacamole for browser-based remote access
Mealie, ntfy, Homepage, Portainer, and other utility services
Monitoring & Reliability
Prometheus and Grafana dashboards
Node Exporter and cAdvisor metrics
Gateway monitoring and packet-loss troubleshooting
Service health checks and notification workflows
Hands-on troubleshooting of modem, routing, DNS, and VLAN issues
Automation & Data Projects
M3 / Power BI Proof of Concept
Built a proof-of-concept pipeline using FastAPI, PostgreSQL, n8n, Grafana,
and Power BI concepts to model shipment forecasting data.
Workflow Automation
Used n8n webhooks and function nodes to receive, transform, store,
and query operational data.
Notification Systems
Connected self-hosted services to ntfy for request alerts, service checks,
and operational notifications.
