Worked on enhancing reliability and testability in large-scale C++ graphics projects, contributing to both google/filament and google/swiftshader repositories. In Filament, addressed a critical stability issue by refining texture parameter management within FMaterialInstance, ensuring mTextureParameters updated correctly when textures were reassigned, which prevented crashes and improved runtime correctness. Later, in SwiftShader, developed a targeted feature to improve AddressSanitizer workflows by introducing weak declarations for ASan global variables, enabling more robust memory-safety detection in CI environments. Demonstrated strong skills in C++ development, debugging, and testing, with a focus on code correctness, maintainability, and improving automated test coverage for graphics systems.
