Worked on the google/closure-compiler repository, delivering twelve features and multiple bug fixes over six months to advance JavaScript and TypeScript compilation. Focused on ES2023 polyfills, class field initialization, and Polymer integration, the work involved deep AST manipulation, code generation, and static analysis using Java and JavaScript. Refactored core compiler passes for normalization, validation, and ES6 class handling, improving code quality and build reliability. Enhanced test tooling and parser robustness, addressed minification stability for Polymer, and ensured accurate metadata in conformance reporting. The approach emphasized maintainability, browser compatibility, and correctness, reducing downstream bugs and supporting modern JavaScript development workflows.
