During August 2025, Mimi Mitor overhauled BBH evaluation subset processing in the UKGovernmentBEIS/inspect_evals repository, addressing issues in dataset construction, prompt management, and solver or scorer selection to ensure correctness across all subset types. She improved code organization and expanded test coverage, enhancing maintainability and reliability for future development. In UKGovernmentBEIS/inspect_ai, she upgraded the beautifulsoup4 dependency to maintain compatibility and runtime stability without requiring code changes. Working primarily in Python and focusing on data engineering, dependency management, and testing, Mimi delivered robust solutions that reduced manual debugging and established a scalable foundation for ongoing evaluation workflow improvements.
