The Developer Experience (DX) Portal is a one-stop solution for API needs, consolidating services such as SDKs, documentation, reactive code samples, test cases, CI/CD integrations, and package publishing on a single platform. The portal's design was iterative, with multiple iterations of wireframes, mock-ups, and final designs, incorporating feedback from the development team to refine its functionality and usability. The design process involved testing mock-ups, addressing issues such as navigation bars, console placement, and button layout, resulting in a cleaner and more functional UI that effectively delivers its functionality to end-users.
