Worked on the EthanThatOneKid/acmcsuf.com repository to enhance mobile usability and maintain code quality in a Svelte-based front end. Delivered a responsive calendar interface by redesigning the layout and toolbar for optimal mobile device interaction, addressing both usability and accessibility. Improved HTML markup consistency by correcting non-void self-closing tags in Svelte components, ensuring adherence to web standards and clearer code structure. Applied consistent styling and markup conventions across the codebase, supporting future maintainability. Utilized Svelte, HTML, and CSS to implement these changes, demonstrating a focus on responsive design and standards compliance while resolving one major bug and delivering one new feature.
