Contributed to the BrownSpaceEngineering/PVDXosV2 embedded operating system by delivering thirteen features and resolving four bugs over two months. Focused on modernizing task management through a pointer-based task list architecture, refactoring command dispatching, and enabling thread-local storage for robust per-task data handling. Enhanced system reliability by stabilizing the build process, improving main loop execution, and fixing driver initialization issues. Expanded test coverage with a dedicated testing framework and automated utilities, streamlining validation of command handling and task onboarding. Worked primarily in C and Makefile, leveraging FreeRTOS, scripting, and low-level programming to improve maintainability, reliability, and onboarding efficiency.
