Worked on the microsoft/codeql repository to enhance JavaScript data flow analysis by recognizing document.defaultView as both a global variable source and an alias for window. Improved the underlying data modeling by refining property access handling, ensuring more accurate representation of global variable references in analysis logic. Expanded test coverage by adding new tests and updating existing ones, and maintained thorough documentation with updated change notes and expected results. Utilized JavaScript and Markdown to implement and document these changes, demonstrating skills in data flow analysis, query optimization, and testing. The work improved reliability and reduced regressions in DOM and global variable handling.
