Embedded Software Developer

Embedded Software Engineer — NexaGrid Technologies

Denver, CO | September 2023 – Present

• Designed and optimized bare-metal C/C++ firmware for 12,000 smart grid sensors, reducing average unit battery consumption by 24% and extending field lifespan by 18 months.
• Integrated I2C, SPI, and CAN communication drivers on ARM Cortex-M microcontrollers, reducing data transmission error rates from 1.4% to less than 0.05% over a 6-month test period.
• Developed automated Python-based hardware-in-the-loop (HIL) test suites that executed 450+ daily regression test cases, cutting hardware validation cycles by 35%.
• Refactored critical sections of RTOS scheduling logic, reducing boot latency by 28% and resolving a memory leak issue that caused 4.2% of devices to crash weekly.

Associate Embedded Developer — Luminate Robotics

Boulder, CO | July 2021 – August 2023

• Collaborated with hardware engineers to debug PCB signal noise issues on 5 robotics prototypes using logic analyzers and oscilloscopes, improving signal integrity by 19%.
• Programmed firmware in C for low-power microcontrollers, reducing RAM footprint by 18% to fit the entire instruction set within a highly constrained 64KB SRAM footprint.
• Drafted 40+ pages of technical API documentation and interface specifications, accelerating onboarding speed for 6 new team members by an estimated 25%.
• Implemented UART and RS-485 serial communication protocols on custom motor drivers, increasing sensor telemetry data reliability by 32% across 20 prototype units.
