Over four months, Mackay contributed to build system modernization and documentation clarity across Auterion/px4-ros2-interface-lib and gazebosim repositories. He updated CMakeLists.txt in the px4-ros2-interface-lib to replace deprecated dependencies, improving compatibility and future-proofing the build process using CMake and C++. In gazebosim/docs, he corrected environment setup instructions and Jetty versioning, reducing onboarding errors. Mackay also enhanced technical documentation in gz-sim by refining terminology for hydrodynamics theory, supporting developer comprehension. Additionally, he stabilized ROS 2 test infrastructure by updating deprecated executor patterns, demonstrating proficiency in ROS 2 integration testing and maintaining system reliability through targeted, maintainable code changes.

October 2025: Delivered a stability fix for the ROS 2 test framework in Auterion/px4-ros2-interface-lib to address deprecation issues. Replaced deprecated rclcpp::spin_some with rclcpp::executors::SingleThreadedExecutor::spin_some and ensured the executor is explicitly added to the node to preserve correct ROS 2 callback handling. This change reduces flaky tests and CI noise, improving reliability for ongoing ROS 2 interface validation and maintenance. Demonstrates strong ROS 2 proficiency, test-infra modernization, and alignment with ROS 2 best practices.

In 2025-09, delivered a targeted documentation clarity enhancement for the hydrodynamics theory in gazebosim/gz-sim. The key change replaces 'much' with 'many' in theory_hydrodynamics.md to reduce ambiguity in the forces description for underwater vehicles. Implemented in commit f7bba964ab8b03ae5590e66f8ea819d5a5d37033 (Update theory_hydrodynamics.md with slight wording change (#3042)). No major bugs fixed this month; the focus was on maintainability and onboarding. This work improves developer guidance and user comprehension while preserving system stability.

Month: 2025-08 — Documentation maintenance and accuracy improvements in gazebosim/docs. Delivered a critical bug fix for the GUI Tutorial by correcting the Jetty version and related environment setup, ensuring users follow accurate CLI argument guidance. This aligns tutorial content with actual runtime requirements and reduces onboarding friction and support inquiries.

July 2025 — Key accomplishments centered on build-system modernization for the Auterion/px4-ros2-interface-lib. Delivered a Vtol example upgrade by replacing deprecated ament_target_dependencies with target_link_libraries in the CMakeLists.txt, aligning with current CMake practices and future-proofing the build. The change is associated with commit e8579957152d4783accd94894c39ed86c002c3b3 (examples: remove deprecated ament_target_dependencies). Major bugs fixed: none reported this month; focus was preventive maintenance to reduce future build risks. Overall impact: improved build reliability, easier toolchain upgrades, and smoother ROS2 integration for the px4-ros2-interface-lib. Technologies/skills demonstrated: CMake modernization, dependency management, ROS2 integration, and cross-project build maintenance.
