Homelab Overhaul Series

A three-part series documenting a major infrastructure migration in my homelab, covering port conflicts, DNS management, and troubleshooting. This project involved migrating Traefik to a dedicated host, updating 31 DNS records, and implementing proper separation of concerns.

AI-Assisted Workflow: Infrastructure work performed using Gemini CLI and CodeX (ChatGPT CLI) with context maintained via GEMINI.md. Website and blog created with Claude. This demonstrates modern CLI-based AI workflows where markdown files provide continuity across sessions and serve as living infrastructure documentation.
