Nguyen Huu Phuc developed a targeted front-end user experience enhancement for the ncc-erp-ams-fe repository, focusing on improving navigation in collapsed sidebar mode within the AMS module. By leveraging CSS and front-end development skills, Phuc standardized hover feedback for submenu items, introducing background color transitions and refining padding and margins to ensure visual consistency. This update addressed usability and accessibility by reducing misclicks and streamlining access to submenu items, aligning with the existing design system. The work demonstrated attention to UI polish and maintainability, with clear commit messages and issue tracking, though the scope was limited to a single feature implementation.
