Summary
👤
SeniorJustin Brzozoski is a firmware-focused software engineer with 18 years in semiconductors and eight years of embedded software experience driving low-power systems, storage devices, microprocessors, and RF digital radios. He combines dual degrees in computer science and electrical engineering to bridge schematic review, PCB bring-up, and low-level bus debugging (I2C, SPI, CAN) with practical firmware delivery. Known for quickly assimilating new technologies, he solves cross-domain problems that span hardware, drivers, and system integration. His open-source contributions to the widely used nRF Connect SDK demonstrate hands-on work in peripheral configuration, modem DFU reliability, and GPS/AT command handling—improving device robustness in constrained environments. Based in Greater Boston, he is a pragmatic embedded C programmer who prefers getting into silicon-level details to ensure real-world functionality. Colleagues rely on him for hard-to-reproduce bug hunts and multi-system root-cause analysis.
