During two months working on the yabukilab/yabuki-b repository, Yu Sato delivered core module enhancements, improved system stability, and overhauled the search experience. Yu refactored PHP backend logic to streamline search flows, integrated and later removed Google Books API search to reduce dependencies, and implemented robust pagination with UI/UX improvements using JavaScript and CSS. By addressing edge-case bugs and cleaning up legacy code, Yu increased reliability and maintainability while enabling faster future development. The work demonstrated depth in full stack development, with careful attention to security, performance, and user experience, resulting in a more scalable and user-friendly web application.
