In the WolfyPay project, my involvement began with the creation of the gateway's visual identity. I was responsible for developing all system screens, both in the web application and the mobile app. This was my first project where I had contact with Design System, an approach that allowed me to create a consistent and cohesive user experience across all screens. Additionally, I assembled a detailed briefing to understand the gateway's final audience and ensured that the screens were intuitive for all users, refining some after usage tests.
