PROFILE
Andy Ross
Andy Ross developed and optimized embedded audio and platform features across the zephyrproject-rtos/sof and sdk-ng repositories, focusing on Mediatek DSP and Zephyr RTOS integration. He modernized timestamp APIs, automated Devicetree DTS generation, and improved build system reliability using C, CMake, and shell scripting. His work included kernel-level performance tuning, toolchain configuration for Xtensa platforms, and stabilization of DMA and IPC tracing. By refactoring build logic and resolving compatibility issues, Andy enhanced platform readiness and developer velocity. The depth of his contributions is reflected in robust driver development, configuration management, and the delivery of maintainable, production-ready embedded solutions.
