Worked on the miru-project/repo, delivering core AniLiberty extension features focused on user experience and maintainability. Developed the extension’s foundational skeleton in JavaScript, implementing user-facing capabilities such as latest releases, detailed views, search, and watch playback. Standardized API integration by configuring a base URL, updating endpoints and metadata, and ensuring consistent API URL usage, which improved reliability and simplified future enhancements. Addressed a critical bug by temporarily disabling the AniLib Liberty repository integration to maintain stability and enable targeted rework. Demonstrated disciplined change management across multiple commits, resulting in improved release hygiene and a scalable foundation for ongoing extension development.
