Worked extensively on the google/closure-compiler repository, delivering 17 features and multiple bug fixes over 14 months with a focus on code modernization, maintainability, and performance. Leveraged Java and JavaScript to refactor core compiler internals, adopting modern language features such as switch expressions, pattern matching, and EnumSet-based handling to reduce complexity and improve efficiency. Enhanced test reliability and code readability by simplifying assertions, tightening encapsulation, and standardizing naming conventions. Addressed data processing correctness and improved build system configuration, while maintaining API compatibility. The work emphasized robust software engineering practices, including unit testing, code cleanup, and performance tuning for long-term stability.
