Developed two privacy-focused features to enhance microphone data protection on Intel platforms, working across the telink-semi/zephyr and thesofproject/sof repositories. Delivered a new Zephyr RTOS driver in C that introduced register-level controls and API functions for dynamic management of microphone privacy, enabling both static and runtime disabling of data streams. In parallel, implemented an IPC handler within SOF firmware to propagate privacy state changes in hardware-managed mode, ensuring seamless integration between firmware and hardware privacy mechanisms. Leveraged expertise in driver development, embedded systems, and IPC communication to deliver traceable, cross-repository solutions that support regulatory compliance and strengthen user privacy.
