This project with the Traffic team, managing API Gateway and Service Mesh, aimed to simplify Traffic configuration management in the DevPortal by reducing manual effort and enabling self-service. Research identified key UX gaps that slowed developers. Following a full design process—research, user insights, wireframes, prototypes, and high-fidelity designs—solutions were iteratively refined with user and stakeholder feedback. The result is a standardized, user-friendly self-service flow that streamlines Traffic tasks, reduces reliance on support teams, and improves efficiency and confidence for developers.
