Worked on the EPF-MDE/git-first-steps repository to introduce a personal user identity artifact, adding a dedicated info file containing a unique username. This feature established a foundation for per-user configuration and improved traceability, supporting future personalization and auditing needs within the project. The implementation followed a clean, minimal approach, with a single, well-scoped commit and clear messaging that adhered to repository conventions. Leveraged Git for version control and file management, and utilized Markdown for documentation. The work focused on maintainability and clarity, ensuring that the new artifact integrates seamlessly with existing project structures and supports ongoing collaborative development.
