01 / About

About

Background across hardware validation, firmware development, and embedded Linux.

Background

I started at Intel Corporation, performing root-cause analysis on signal integrity failures in server-grade CPUs, GPUs, and DDR5 memory subsystems.

At Collins Aerospace, I moved into hardware validation and test automation for avionics systems, including digital signal processing work for real-time sensor data.

Current focus

I am currently an Embedded Systems Engineer at Langmuir Systems, where I design PCBs and develop firmware for CNC and laser control systems.

I also do freelance firmware work, including bare-metal and RTOS development and custom embedded Linux BSPs. I hold a B.S. in Electrical and Computer Engineering from Oregon State University.
