Giovanni Andrews Lima developed a dedicated headphone product catalog page for the Gustavo-Mitsuo87/Site-PW-Sony repository, focusing on a UI/UX refresh to enhance product discovery and branding consistency. Using HTML and CSS, Giovanni implemented a card-based layout with integrated promotional imagery, responsive design, and improved navigation and search features. The work included iterative UI refinements and asset integration, resulting in a maintainable front-end structure that supports faster time-to-market for new products. No critical bugs were reported, and minor polish was addressed during rollout. The project demonstrates solid application of CSS styling and front-end development skills within a focused, single-feature scope.
