Rockstar🎓
Top SchoolJędrzej Ciupis is a software engineer with 8 years of experience specializing in embedded systems, real-time operating systems, and IoT, now on the engineering team at Google. He spent five years at Nordic Semiconductor developing and refining IEEE 802.15.4 PHY/MAC drivers and integrating them into the Zephyr RTOS for nRF52/53/54 platforms, contributing fixes, security enhancements, and hardware-specific features like FEM and nRF21540 support. An active open-source contributor, he has notable commits to the Zephyr and nRF Connect SDK ecosystems, including raw radio mode, Key Identifier Mode improvements, and network CPU refactors that improved reliability on Nordic SoCs. He holds advanced degrees in AI and automatic control/robotics, blending low-level firmware expertise with a strong background in control systems and machine intelligence. Colleagues describe him as detail-oriented and pragmatic, often uncovering subtle hardware-software interaction bugs such as timer signedness and Rx error edge cases.
