Federica Uda developed foundational features for the nh-spipitone/DataAnalyst-course repository, focusing on project scaffolding and an interactive FizzBuzz tool. She established a modular directory structure and introduced placeholder files to support future scalability and maintainability. Using Python scripting and command-line interface techniques, Federica refactored input handling to enable user-defined parameters within the FizzBuzz feature, allowing for a more configurable and interactive experience. Her work emphasized clean file management and maintainable code organization, laying a solid groundwork for subsequent development. While no bugs were reported or fixed, the depth of her contributions centered on robust architecture and user-focused configurability.
