Worked on the zezo2323/online_store repository to enhance the user interface and streamline project assets over a one-month period. Focused on front-end development using HTML and CSS, the work included refining the navigation menu by adding and then removing a placeholder item to improve clarity and usability. Overhauled the user authentication interface, creating a new login page and refining its layout for a better user experience. Additionally, removed an unused image asset to reduce project bloat and improve maintainability. No critical bugs were reported, allowing the focus to remain on UI/UX design polish and overall front-end maintainability.
