Worked on the arthur-engine repository to enhance evaluation workflows and data integrity within a one-month period. Focused on improving the Evaluator UI by refining data retrieval, reorganizing detail views, and introducing a configuration modal to streamline user interactions. Addressed user experience issues by ensuring form fields in the Add Row dialog cleared after submission, preventing outdated data from appearing. Improved dataset integrity by guaranteeing new columns were added with default values to existing rows, reducing the risk of data loss. Utilized React, TypeScript, and JavaScript to deliver targeted frontend enhancements and collaborated closely to reinforce code quality and maintainability.
