Johanna Arango Quiroga contributed to the NULabNortheastern/digitalassignmentshowcase repository by developing and organizing course documentation and digital learning assets over a two-month period. She focused on improving the structure and clarity of Markdown-based materials, updating READMEs, and refining folder hierarchies to enhance accessibility for students and instructors. Her work included adding new PDF resources, updating StoryMap content, and managing the lifecycle of WordPress and Wix assets to ensure up-to-date materials. Johanna’s technical approach emphasized documentation best practices and repository hygiene, resulting in well-organized, easily navigable resources with clear version control and no reported defects during the review period.
