About

Systems-focused electrical engineer specializing in embedded Linux, microcontroller development, and end-to-end product deployment. At Xonar Technology I've written firmware for microcontroller subsystems, designed serial communication upgrades, and led IEC/UL and FCC/CE certification from start to finish. My path wasn't linear — a decade in education and technology training sharpened my ability to communicate complex systems clearly and deliver at scale. I returned to university to formalize what I'd been doing as a hobbyist for decades, graduating from FIU's College of ECE in 2023. C/C++, Python, UART/SPI/I²C, Docker, FPGA, Linux. I work best where hardware meets software and someone needs to own the full stack.
