Worked on Tencent/libpag and Tencent/tgfx, focusing on stability, performance, and cross-platform compatibility for native UI animation and rendering systems. Addressed memory leaks and improved memory management in C++ by refining animation lifecycle handling and implementing iterative destruction for large SVG DOM trees. Enhanced build-system compatibility for iOS and macOS frameworks using CMake, and optimized VSync synchronization on OHOS with thread-safe initialization via std::call_once. Integrated ArkUI V2 state management to streamline component architecture and boost performance. These efforts resulted in more reliable UI experiences, smoother developer workflows, and improved thread safety and startup reliability across multiple platforms.
