During October 2024, Hannah focused on enhancing the Fish-stocks Explorer within the owid-content repository by simplifying its dataset structure. She removed the 'Fishing intensity relative to the management target' column, reducing redundancy and streamlining data exploration for users. This change, implemented using Python and Git, improved dataset clarity and maintainability while supporting reproducibility through a well-documented commit history. Hannah’s work addressed business needs for clearer, more accessible data without introducing new bugs, and aligned with ongoing goals for dataset quality. The depth of her contribution lay in thoughtful data modeling and careful attention to long-term maintainability within the project.
