Worked on the ppy/osu repository to deliver a targeted UI improvement for the editor, focusing on timeline visual tuning. Adjusted the timeline blueprint’s color intensity from 0.9f to 0.6f using C#, reducing visual prominence and enhancing clarity for content creators during editing. This change aimed to streamline the editing workflow by minimizing visual noise and making timeline elements less distracting. The implementation involved precise code-level modifications and was committed with clear traceability, reflecting disciplined use of Git. Demonstrated skills in game development and UI development, with an emphasis on maintainable code and thoughtful user experience enhancements within the editor.
