During February 2025, contributed to the GopeedLab/gopeed repository by implementing a Dynamic Title Bar Theme for desktop platforms using Flutter and Dart. This feature enabled the application’s title bar to automatically adjust its appearance based on the current system theme, enhancing visual consistency and user experience across operating systems. The work involved centralizing theming logic to improve maintainability and aligning commit messages with issue references for better traceability. Additionally, addressed a Windows-specific bug that previously prevented reliable theme switching for the title bar. The focus on cross-platform UI development demonstrated attention to both technical detail and user interface polish.
