Sharanya Saha
Sharanya Saha developed support for the ArtMethod V2 Streaming Trace Format in the google/perfetto repository, introducing the ArtMethodV2Tokenizer to parse new binary, delta-encoded ART Method v2 streaming traces. By leveraging C++ and advanced binary parsing techniques, Sharanya enabled more efficient handling of trace data, reducing both CPU overhead and trace file size on Android devices. The work addressed a compatibility and parsing issue with the ART Method v2 format, improving reliability for performance diagnostics. This contribution demonstrated depth in Android development, performance optimization, and code collaboration, resulting in faster tracing and analysis workflows for performance engineering teams.
