PROFILE
Wuweikai
Wuweikai contributed to the google/perfetto repository by developing end-to-end support for visualizing Android Systrace CPU frequency limit events, extending the trace processor to parse new ftrace events and integrating them into the Perfetto UI using C++ and data visualization techniques. He also addressed a clock synchronization issue in PerfettoUI for Android logcat traces, improving reliability by aligning logcat handling with other trace types through targeted debugging and software engineering. Additionally, Wuweikai updated documentation to reflect repository restructuring, ensuring onboarding materials remained accurate and consistent. His work demonstrated depth in system tracing, trace processing, and technical writing across multiple domains.

Mar 1, 2026March 2026 – google/perfetto: Documentation-focused update for SDK fetching flow following repo restructuring. Delivered concrete changes to tracing-sdk.md to reflect removal of the perfetto/sdk directory and introduced alternative methods to obtain SDK source files. Aligned with examples/sdk/README.md and linked to issue #5008 for traceability. No major bugs reported this month. Impact: improved onboarding, reduced support overhead, and ensured developer guidance matches current repo layout. Skills demonstrated: documentation best practices, cross-repo consistency, version-control traceability, and ability to synthesize repository changes into user-facing docs.

Feb 1, 2026February 2026: Delivered a critical PerfettoUI clock synchronization fix for loading a single logcat file, improving reliability and user experience when handling Android logcat traces. This change ensures proper clock handling for logcat traces by adding SetGlobalClock for the kAndroidLogcatTraceType, aligning with other trace types and resolving the clock_sync_failure_unknown_source_clock error.

Aug 1, 2025August 2025: Implemented Android Systrace CPU frequency limit events visualization in Perfetto, enabling end-to-end parsing and UI display of CPU frequency limit data within Android trace analyses. This work extends the trace processor to parse cpu_frequency_limits ftrace events, integrates with the Systrace line parser, and provides visualization in Perfetto UI for Android Systrace usage, complementing existing proto-based data.
