PROFILE
Alessio Balsini
During November 2024, Balsini enhanced the google/perfetto repository by focusing on kernel tracing reliability and observability under high concurrency. They addressed missed kretprobe events in Android binder scenarios by increasing the default maxactives value, improving event capture during system load. Balsini also implemented the export of kprobe_profile statistics, adding protobuf-based messages and parsing logic to record hits and misses, and flagging traces for data loss when necessary. Working primarily in C++ and protobuf, Balsini demonstrated expertise in system programming, kernel development, and performance analysis, delivering targeted improvements that reduced data gaps and enabled deeper diagnostic capabilities for performance optimization.
