Worked on the google/perfetto repository to enhance Android observability and performance tracing by building features such as AndroidTrackEvents for monitoring service and content provider state changes. Leveraged Java, C++, and Protocol Buffers to implement SDK instrumentation, static track name support with compile-time safety, and native function integration for streamlined Android framework usage. Refactored exception handling and improved test reliability to ensure robust API correctness and maintainability. Focused on reducing overhead in privileged processes by relocating registration checks and enabling dynamic tracing readiness. The work emphasized cross-layer consistency, structured messaging, and efficient data collection to support diagnostics and developer productivity.

Apr 1, 2026April 2026: Focused on hardening the Java SDK trace naming surface and strengthening test reliability for google/perfetto. Delivered static track names support with compile-time safety, enabling lower layers to distinguish static vs dynamic names and optimize Westworld uploads by ignoring dynamic names by default. Updated the build to enable error-prone_annotations for compile-time checks. Improved test coverage and API correctness for PerfettoTraceTest.

Feb 1, 2026February 2026 monthly focus centered on performance optimization for Perfetto system-wide tracing. Delivered a new initialization check in the Java SDK to determine if Perfetto is configured for system-wide tracing, and relocated the registration status check from the Android framework to the SDK to reduce overhead and SELinux risks in privileged processes.
