Pohengshen
During March 2026, Poh Eng Shen developed the Ftrace Scheduling Group Tracking feature for the google/perfetto repository, introducing the sched_group_tracker event to enhance visibility into CPU scheduling groups. This work involved designing new protocol buffer definitions and implementing corresponding C++ event descriptors, integrating them into the existing code generation and test data pipelines. By enabling more granular tracing of scheduling decisions, Poh laid the foundation for improved root-cause analysis and performance optimization. The approach demonstrated depth in system programming and performance tracing, ensuring repository readiness with aligned documentation and comprehensive test coverage, while leveraging expertise in C++ and ProtoBuf.
