Worked on the uu-semp/swedish-learning-app-2025 repository to deliver a settings modal that enhances user customization and offline experience. The implementation involved updating the HTML structure to include a modal and an accessible open button, while JavaScript modules managed the logic for adjusting and persisting user preferences such as volume and sound effects. Leveraging localStorage, the settings are saved locally, ensuring that user choices persist across sessions. The work utilized front end development skills, including CSS and JavaScript, and established a foundation for future accessibility improvements and feature expansion, focusing on maintainable code and a more personalized user experience.
