Rockstar🎓
Top SchoolMaciej Baczmański is a software engineer specializing in embedded systems and IoT with three years of professional experience and a growing track record at Nordic Semiconductor and now Google. He has contributed significant low-level work to prominent open-source projects—Zephyr and OpenThread—implementing radio driver fixes, CSL and ACK improvements, and diagnostic features that improve low-power and networking reliability. Comfortable across SDKs and platform integrations, he has also updated nRF Connect documentation with real-world power data and sample improvements for Matter/OpenThread use cases. A background in automation and robotics from AGH University complements his hands-on firmware skills, and his mentoring and leadership roles in student organizations hint at strong collaboration and project coordination abilities. Notably, his contributions include upstreaming OpenThread changes and adding unit tests, showing attention to maintainability and quality beyond feature work.
