Worked on repository hygiene improvements for slds-lmu/lecture_i2ml, focusing on streamlining file tracking and maintenance workflows. The main feature involved removing the .gitignore file to standardize how files are managed by Git, which established a more predictable post-merge file state and reduced ongoing maintenance overhead. This effort included consolidating cleanup tasks after merging multiple branches, ensuring a stable baseline for future development. Demonstrated strong version-control discipline and collaborative practices throughout the process. Utilized skills in file management, Git, and version control, with work primarily involving Markdown, R, and TeX to support documentation and code organization within the repository.
