Worked on improving repository hygiene and cross-platform consistency for the Automattic/harper project by addressing formatting and artifact management issues. Focused on configuration management using EditorConfig, Git Attributes, and Git to standardize line endings to LF across Windows, macOS, and Linux, which minimized unnecessary diffs and reduced CI noise. Consolidated maintenance into two commits that updated .gitignore to exclude Typst LSP-generated PDF artifacts and introduced .editorconfig and .gitattributes files. This approach streamlined onboarding for new contributors, improved version control practices, and ensured a cleaner development environment, reflecting a methodical approach to repository maintenance and cross-platform tooling awareness.
