During October 2025, Skye Galaxy refactored the ros2/rclcpp repository to centralize GraphListener management, enabling shared access across multiple nodes. By moving the GraphListener from the NodeGraph to the Context, Skye ensured that initialization occurs at Context startup and shutdown is handled via a registered callback, improving lifecycle reliability and coordination between nodes. This foundational change, implemented in C++ with a focus on ROS2 and software architecture, reduced code duplication and enhanced maintainability for multi-node graph introspection. The work demonstrated a deep understanding of system design and refactoring, addressing cross-node resource sharing and lifecycle management within a complex codebase.
