PROFILE

Paul Bone

Worked on the mozilla/gecko-dev repository over two months, focusing on PHC telemetry and memory management improvements. Enhanced observability by cleaning up legacy telemetry, extending memory usage reporting, and simplifying configuration. Refactored memory management code to centralize locking, reorganize data structures, and replace macros with safer functions, improving both safety and maintainability. Improved test reliability by refining PHC exhaustion tests and correcting variable naming inconsistencies, which reduced flaky CI runs and maintenance overhead. Utilized C++ and YAML, applying skills in debugging, concurrency control, and performance optimization to deliver more robust system programming and streamlined telemetry management for ongoing development.

July 2025 (mozilla/gecko-dev) — Focused on stabilizing critical PHC testing infrastructure and improving code reliability. Delivered two primary outcomes: 1) PHC Exhaustion Test Reliability Enhancements to increase test reliability and maintainability by adjusting probabilities, restoring defaults after runs, refining allocation tracking, and leveraging PHC statistics for dynamic allocation; 2) PHCManager Typo Fix correcting a misspelled page_reuse variable across constants and registration callbacks to prevent misbehavior and improve consistency. These changes improve CI stability, reduce flaky test runs, and lower ongoing maintenance costs. Technologies demonstrated include C++ code changes, test engineering for PHC infrastructure, and effective version-control hygiene.
