Industrial Automation Technician | Python Builder | Systems Engineer

“The question isn’t who is going to let me — it’s who is going to stop me.”
— Ayn Rand


About Me

I build systems that work — industrial, electronic, digital, or philosophical.
From PLCs on factory floors to Python scripts on Raspberry Pis:

  • Industrial Automation Technician — Smucker’s Uncrustables / Leprino Foods / Cargill One Protein
  • Hobbyist Engineer — circuits, sensors, relays, CAN-bus, hydroponics, 3D printing
  • Programmer — Python, CircuitPython, Arduino, Linux automation, Raspberry Pi clusters
  • Objectivist — pro-reason, pro-capitalism, anti-bullshit
  • Metalhead — Metallica | Gojira | Slayer | Pantera | Machine Head | Sepultura

My Projects

PepperCAN

A modular CAN-bus hydroponic control network — sensor nodes, relays, and displays tied together by a RP2040 controller.

  • Features: pH / Temp / EC telemetry, automatic nutrient dosing, MQTT + Home Assistant integration
  • Stack: CircuitPython, CAN, I²C multiplexer, Qualia displays, Docker HA bridge

Home Server Ecosystem

Self-hosted architecture running:

  • Pi-hole + Unbound DNS
  • Tailscale VPN
  • Navidrome music server
  • Home Assistant dashboards
  • MQTT broker + automation scripts
  • rclone + RAID NAS backups

DIY & Metal Projects

  • Custom aluminum + brass casting
  • Vacuum tube preamps and audio PCB design
  • Reloading & precision shooting gear — sub-½" groups at 100 yards
