╔══╡ LOGON BULLETIN ╞═══════════════════════════════════════════╗
I write firmware for microcontrollers, mostly ARM Cortex-M and the occasional 8-bit part that refuses to die. Over 15 years I have shipped firmware for 23 products, from smart water meters to avionics test rigs. My current codebase fits in 384 KB of flash and I intend to keep it there.

Senior Embedded Developer · Cactus Wire Labs

Phoenix, AZ · 2019–present
  • Lead firmware on a 6-person team for an industrial sensor line, 4 SKUs, 60k units/yr
  • Cut boot time from 2.1 s to 340 ms by rewriting the init sequence and dropping 2 vendor libs
  • Built a HIL test bench that catches regressions in 11 min instead of a 2-day field cycle
[2]

Embedded Developer · Sonoran Avionics Test Co.

Tempe, AZ · 2014–2019
  • Wrote ARINC 429 and CAN interface firmware for 3 bench test units used at 40+ repair shops
  • Reduced field RMA rate from 4.2% to 0.9% after tracing a brownout bug to one capacitor spec

Firmware Engineer · Mesa Metering Systems

Mesa, AZ · 2010–2014
  • Maintained C firmware for a smart water meter, 250k deployed units, 10-year battery target
  • Trimmed sleep current from 18 µA to 6.5 µA, which added roughly 3 years of battery life
