Oriol Puig focused on enhancing the Photo Uploader component within the SUI-Components/sui-components repository, delivering a more reliable and accessible user experience. He refactored React components using JavaScript to ensure upload responses were accurately merged into the file list, preserving all relevant properties and maintaining correct photo previews. Oriol addressed accessibility by standardizing internal Button elements to use type='button', preventing unintended form submissions. He also improved component reliability by passing external props to the rotate action and migrating prop usage to reduce regression risk. His work demonstrated a solid grasp of front-end development and component refactoring best practices.
