Worked on the thorvg/thorvg repository to enhance SVG rendering performance and stability using C++ and advanced graphics programming techniques. Focused on optimizing the SVG loader by skipping unnecessary ClipPaths and Filters during scene construction, which reduced redundant draw calls and improved rendering efficiency for complex SVG files. Addressed a critical bug that previously caused infinite loops when circular references appeared in <use> elements, thereby increasing reliability and predictability. Improved code maintainability by clarifying loader responsibilities and enhancing documentation. Demonstrated strong skills in algorithm optimization and debugging, delivering targeted improvements that streamlined the rendering pipeline and reduced crash risk for end users.
