Projects
A collection of projects that I have made over the years. I'm always doing a project so this list is not comprehensive, only focusing on the recent highlights.
KubeNodeSmith: Implementing the NodeClaim Model for Proxmox
Replicated the flexible NodeClaim pattern to drive provisioning against the Proxmox API. The system uses PXE-booted NixOS flakes and shared configuration snippets for a reproducible, declarative scaling flow.

ESP32 Garage Opener
Starting from a frustration of locking myself out of my apartment a few time, but always having my phone on me. I decided to make a web controlled garage door opener.
