Barclays Pingit was the first service to offer mobile payments using only your phone number. At its peak, it had over 1 million active users and saw £300 million transactions every year. I was asked to lead the visual design team in the re-design of the entire app, creating an entirely new set of design principles, motion principles and iconography. The entire project spanned a year and was widely praised on launch. As part of the project, we delivered a comprehensive design system to ensure a seamless transition for future designers as the product grew.
