Portrait of Matthew, aka TechDufus

You can call me Dufus.

Platform Engineer / Agentic Engineer

Hello from the command line

I break things, fix them, and write down what actually worked.

Platform engineering notes from a guy who lives in tmux. Real incidents, homelab rebuilds, and AI agent experiments.

Hello, I'm TechDufus.

I'm Matthew, but most people online know me as TechDufus. I started in PowerShell, moved into Kubernetes platform work, and now spend most of my time on agentic workflows.

If I repeat something twice, I script it on the third pass.
