Rockstar🎓
Top SchoolMaciej Fabia is a Lead Embedded Software Engineer based in the Cracow metropolitan area with six years of professional experience and a broader firmware background dating back to 2011. He has progressed from hands-on embedded developer to technical lead roles at ASSA ABLOY and previously delivered Bluetooth and IoT firmware at Nordic Semiconductor. Maciej contributed to the high-profile nRF Connect SDK, adding and integrating the Zigbee stack, IEEE 802.15.4 radio API work, crypto features, and sample enhancements—demonstrating deep protocol and radio-layer expertise. He combines formal training in automatics and robotics from AGH University of Krakow with pragmatic system-level engineering, often tackling radio, timing, and security trade-offs in constrained devices. Known for extending reference samples (like light bulb scenes) and adding delayed packet and NCP support, he brings a product-minded approach to open-source and internal SDK development. Colleagues would describe him as a practical problem solver who translates complex wireless standards into reliable, test-covered firmware.
