Worked on optimizing wakeup event parsing in the Fuchsia Trace Processor within the google/perfetto repository, focusing on improving trace loading performance. Addressed a critical bottleneck by replacing an O(N) scan of the thread state table with a hashmap lookup, which eliminated quadratic behavior and reduced load times for large traces. The solution was implemented in C++ with attention to data structures and performance optimization, and included unit testing to ensure reliability. This targeted enhancement improved code maintainability and established a foundation for further optimizations in the trace loading pipeline, reflecting a methodical approach to performance engineering and code quality.
