In December 2024, Nina Schaefer delivered a Personal Business Card UI overhaul for the cosdpp/cos24-cards repository, focusing on enhancing the homepage’s professional and educational presentation. She restructured the HTML and CSS to create a dedicated section, integrated external fonts, and implemented a responsive design using a viewport meta tag to ensure consistent branding across devices. Nina also added a binary image asset to support the new visuals. Her work established a foundation for future personalization features, improved user experience, and strengthened personal branding, demonstrating solid front end development skills with a focus on maintainable, well-structured code.
