During April 2025, J. Kim focused on enhancing cross-platform build stability for IOKit-dependent code in the AvaloniaUI/angle and google/dawn repositories. By leveraging C++ and CMake, Kim addressed compilation failures on tvOS and macOS by implementing conditional inclusion of the IOKit.framework within build configurations. This approach ensured that SystemInfo_macos.mm and related components compiled reliably across both platforms, reducing platform-specific errors and improving CI reliability. Kim’s work demonstrated a strong grasp of build system configuration and cross-platform development, resulting in two bug fixes that accelerated feature delivery and maintained code health without introducing new features during the period.
