Alexander Yanovskyy focused on improving the build system for the shadPS4 repository by addressing the handling of the optional Discord RPC feature. He implemented robust conditional compilation in C++ to ensure that the ENABLE_DISCORD_RPC flag reliably includes or excludes related code, and refined include path management to prevent build errors when the feature is disabled. This work reduced the risk of CI and local build failures, making future maintenance of optional features more straightforward. By leveraging his expertise in build systems and C++ development, Alexander delivered a targeted bug fix that enhanced the reliability and maintainability of the project’s build process.
