Summary
🤩
Rockstar🎓
Top SchoolBartosz Miller is a Senior Software Test Developer based in Wrocław with a strong background in end-to-end hardware and embedded systems design, spanning requirements, schematic and PCB design, testing, and documentation. He brings over a decade of hands-on experience across telecom, automotive, medical, and industrial projects, and currently focuses on power management and peripheral benchmarking for embedded IoT platforms at Nordic Semiconductor. At Nokia he led hardware integration and built Python tools for RF, 3GPP compliance and high-speed interface testing, reflecting a blend of system-level thinking and practical test automation. His open-source contributions to high-profile projects like Zephyr and the nRF Connect SDK center on expanding device-driver test coverage and optimizing low-power peripheral behavior—work that directly improves real-world product reliability and battery life. Comfortable moving between firmware, FPGA, and test frameworks, he has a track record of turning complex hardware requirements into verifiable, production-ready systems. His atypical strength is combining deep electrical engineering skills with reproducible software testing methodology to shave power and failure modes out of embedded products.
