Worked on the lichess-org/mobile repository to enhance the engine evaluation gauge in the Lichess mobile app, focusing on aligning its behavior with the web interface. Implemented a feature that displays 0.0 without a sign for draws and neutral positions, reducing ambiguity and improving clarity for users during game analysis. Utilized Flutter and Dart to update the UI logic, ensuring consistent rendering of neutral values and preventing misleading sign artifacts in edge cases. Added automated tests to verify correct display and increased regression safety, while also improving test formatting and documentation to support maintainability and code quality within the project.
