Worked on the hack-duke/portal.hackduke.org repository, focusing on front end development and responsive design using React, JavaScript, and CSS. Delivered two features over two months, including optimizing the HeroBackground component for mobile devices by hiding background elements on screens under 600px, which improved layout stability and visual consistency. Enhanced the login flow by extending the countdown deadline and addressing a date bug, ensuring accurate onboarding for users. Emphasized a mobile-first approach and maintained clear documentation throughout the process. Prioritized minimal layout shifts and reliable user experience, demonstrating attention to detail in both feature implementation and interface refinement.
