Worked on the MIT-SPARK/Awesome-DCIST-T4 repository, focusing on dependency maintenance by updating the spot_tools submodule reference to a newer commit. This effort centered on improving build reproducibility and ensuring alignment with the latest external tooling, while deliberately avoiding changes to the main codebase to minimize risk. Demonstrated skills in Git submodule management, dependency pinning, and cross-repository coordination, which helped maintain environment consistency and reduce drift between internal and external components. No bugs were addressed during this period, as the primary contribution was the careful management of dependencies to support stable builds and ongoing compatibility with evolving external tools.
