PROFILE
Carlos Caballero
Over a two-month period, contributed to the google/perfetto repository by developing and integrating a comprehensive ETM trace analysis pipeline. This work included building the PerfTracker class for unified performance tracking and establishing foundational ETM importer capabilities, enabling end-to-end ingestion and decoding of ETM trace data. Leveraging C++, Python, and GN build systems, implemented memory mapping, binary file parsing, and instruction range infrastructure to support detailed trace analysis and integration with the SQL engine. Enhanced maintainability and onboarding through updated documentation and build configurations, focusing on robust system integration, performance analysis, and support for embedded systems workflows without introducing regressions.
