During October 2024, Jizon focused on frontend development for the lunny/gitea repository, addressing a critical bug on the Activity page. By analyzing the root cause of undefined errors, Jizon refactored the way activityTopAuthors was accessed, replacing the fragile .value pattern with direct array access in Vue. This targeted fix stabilized the rendering of the activity graph and author information, reducing runtime errors and improving data consistency for users. Although the work centered on a single bug fix rather than new features, it demonstrated careful attention to UI reliability and a solid grasp of JavaScript and modern frontend practices.
