Worked on the mozilla/gecko-dev repository to deliver four front-end features over two months, focusing on responsive design and UI consistency. Developed a reusable AboutWelcome layout using React and CSS, introducing a useMediaQuery hook and conditional styles to ensure consistent cross-device presentation and configurable padding. Enhanced user experience by addressing layout inconsistencies and improving accessibility. Contributed to UI/UX by refining notification targeting to prevent overlap with feature callouts and adding an MDN Web Docs card in Firefox Preferences. Applied SCSS and JavaScript to improve submenu button sizing, ensuring visual consistency and maintainability across the browser’s interface and settings.
