Contributed foundational data scaffolding to the glaucioscheibel/gcso2025-1 repository by establishing a structured file management system within the Carlos directory. Focused on creating and updating several text-based data files, the work involved initializing content, refining file contents through iterative edits, and maintaining data hygiene by renaming and removing files to streamline the dataset. All changes were carefully documented with clear commit messages to ensure traceability and facilitate downstream processing. Leveraging skills in file management and working primarily with text files, the contributions laid the groundwork for scalable test data provisioning and improved the organization of project assets for future development.
