In January 2025, Michal Bukowski developed two privacy-focused features to enhance microphone data protection on Intel platforms. Working across the telink-semi/zephyr and thesofproject/sof repositories, he implemented a Zephyr RTOS driver that provides register-level controls and API functions for dynamic or static management of microphone privacy. He also added an IPC handler in SOF firmware to propagate privacy state changes in hardware-managed mode. Using C and leveraging skills in driver development, embedded systems, and IPC communication, Michal’s work improved user privacy and regulatory compliance, demonstrating depth in hardware interaction and cross-repository collaboration with clear, traceable commits.
