Surbhi Kadam enhanced the google/perfetto repository by delivering a feature that upgraded SurfaceFlinger layer tracing with richer per-corner radii data. She introduced the effective_radii field to the LayerProto schema and migrated its type to CornerRadiiProto, enabling more granular diagnostics of rendering pipelines. Her work focused on evolving Protocol Buffers schemas and coordinating cross-repository proto upgrades to improve the observability of SurfaceFlinger layers. By applying strong data modeling and schema definition skills in protobuf, Surbhi addressed the need for detailed performance traces, supporting more effective root-cause analysis for rendering issues without introducing any new bugs during the development cycle.
