PROFILE
Alex Attar
During two months contributing to google/perfetto, Ali Attar enhanced ETW trace ingestion and UI rendering for Windows. He optimized the ETW parser in C++ by replacing dynamic maps with static constexpr arrays, improving performance and reliability. Ali extended the parser to capture thread wait reasons, enriching the thread_state table and enabling more detailed blockage visualization in the UI. He also improved UI readability by labeling anonymized threads and expanded translation coverage for thread states, using TypeScript and i18n techniques. His work demonstrated depth in system programming, performance analysis, and front-end development, resulting in faster, more insightful, and accessible trace diagnostics.
