Networking first
Understand DNS, routing and reachability before debugging applications.
Infrastructure / Homelab
Inside my homelab
A guided tour of the technologies I use to learn infrastructure engineering. Choose a layer, then select a component to explore its purpose and the problems I've worked through.
Conceptual architecture, not a live network map. Connections are simplified and do not imply every service runs on the same host. No private network details or real-time service status are exposed.
How I approach the lab
Reproducible services
Use Compose files and persistent storage to make services easier to maintain.
Learn by troubleshooting
Investigate real issues, from Proxmox quorum to VPN health checks and Cloudflare deployments.
