Contributed to the videolan/vlc repository by modernizing the build system to GNU++17/GNU17 standards and enhancing cross-platform compatibility, particularly for OS/2. Addressed build failures by refining Makefile and Meson configurations, resolving symbol duplication, and adding missing headers. Improved video output stability through memory management fixes and code cleanup, while also strengthening audio subsystem reliability by eliminating potential deadlocks and introducing monitoring features. Enabled new platform capabilities by scaffolding KAI plugin support and expanding OS/2-specific modules. Demonstrated expertise in C, C++, and build automation, focusing on maintainability, robust system programming, and seamless integration of new features across diverse environments.
