During May 2025, Lizzi worked on the Shopify/opentelemetry-ebpf-profiler repository, focusing on stabilizing frame handling under concurrent access. She addressed a race condition in the reporter’s FrameKnown logic by upgrading the lock from read to write, ensuring exclusive access during frame map operations. This targeted fix, implemented in Go, prevented data corruption and inconsistent states, especially under high telemetry load. Lizzi’s work leveraged her skills in concurrency, debugging, and system programming to enhance the reliability of telemetry data collection. Although the period involved a single bug fix, the solution demonstrated careful attention to data integrity and robust concurrent system design.
