Aife Ni Chofaigh's portfolio highlights several projects from April 2009 including a website redesign for a local business, user experience testing for a new software application, and wireframes created for a proposed mobile app. The website redesign modernized the design and improved navigation and content organization to better meet customer needs. User experience testing identified areas for improved usability and reduced confusion. Wireframes for the mobile app outlined the key screens and interactions to demonstrate the concept for the new product.
