Worked on the google/perfetto repository to enhance Windows ETW trace ingestion and UI experience over a two-month period. Focused on C++ and TypeScript, the work included optimizing ETW parser performance by replacing dynamic maps with static constexpr arrays for faster task state lookups and extending the parser to capture thread wait reasons, enriching blockage visualization in the UI. Improved robustness by refining wait reason parsing logic and enhanced UI readability by renaming anonymized threads and expanding translation coverage for thread states. The contributions combined system programming, performance analysis, and front-end development to deliver faster, more informative, and accessible trace diagnostics.
