Andrew Perepech developed and integrated audio platform drivers, hardware abstraction layers, and build system enhancements for Mediatek SoCs in the zephyrproject-rtos repositories. He delivered end-to-end bring-up for platforms like MT8365 and MT8188, implementing low-level drivers in C and CMake, and enabling audio hardware interaction through device tree and AFE integration. His work included toolchain and CI/CD integration, debugging improvements, and platform configuration for reliable DSP operation. By addressing initialization order, timer stability, and test infrastructure, Andrew ensured maintainable, scalable support for embedded audio systems, demonstrating depth in embedded systems, driver development, and cross-platform build management.

September 2025 monthly summary for zephyrproject-rtos/zephyr-testing. Delivered core Mediatek DSP clock and platform configuration support, improved testability through Twister config updates, and upgraded HAL integration to support MT8186/88 and MT8196 DSP processors. These efforts accelerate hardware bring-up, enable broader testing outside the SOF environment, and improve CI reliability across platforms.

April 2025 monthly summary focused on stabilizing MTK debug paths in the zephyrproject-rtos/sof area. Delivered a critical initialization-order fix that prevents a crash in DEBUG builds by ensuring ipc_init() runs after scheduler_init_ll(), addressing an MTK-specific dependency and improving debug reliability. The change reduces debugging churn, strengthens CI stability for MTK targets, and enhances code health through a targeted patch with a single commit reference. This work demonstrates solid platform debugging, init sequencing, and cross-team collaboration, delivering clear business value by reducing time-to-debug and increasing release confidence.
