Worked on the mozilla/build-a-b repository over two months, delivering eight features and a security fix focused on onboarding, animation, audio, and UI/UX improvements. Enhanced first-run navigation and onboarding by refining welcome screens and updating card visuals using React and TypeScript. Integrated Lottie animations and optimized animation layering for consistent cross-browser experiences. Modernized audio management by migrating to Howler.js, introducing a preloader hook, and implementing audio-context recovery for mobile and iOS reliability. Upgraded Next.js to address a critical CVE, improved header readability, and removed legacy audio tests, resulting in a more robust, maintainable, and user-friendly application across platforms.
