Worked on the o-hadalin/portfolio-2.0_g.5 repository to deliver a new About Me section for a personal portfolio site, focusing on both structure and responsive design. Used HTML for semantic markup and CSS for comprehensive styling, ensuring the section adapts seamlessly across mobile, tablet, and desktop devices. Addressed typography, spacing, imagery, and background behavior to align the visual presentation with branding and enhance user experience on all platforms. Iteratively stabilized the feature through targeted commits, including fixes for image rendering and background issues. This work established a scalable foundation for future content expansion while demonstrating attention to cross-device front end development.
