Worked on the mozilla/gecko-dev repository to enhance the WebAssembly engine by delivering five features and addressing a critical bug over two months. Focused on simplifying configuration through the removal of legacy flags, optimizing memory sharing for builtin modules, and refactoring internal range representations to streamline parsing and compilation. Improved runtime reliability by standardizing error handling and aligning compatibility with V8. Addressed stack result management in the Ion pipeline by introducing a dedicated node for reference types and implemented explicit error handling for parameter overflows. Utilized C++, JavaScript, and build system configuration skills to improve maintainability, performance, and code clarity.
