Reqwest: UX design for browser-based API testing

Reqwest needed an API-testing interface where people could send everyday requests quickly without losing the context needed for teamwork and more advanced workflows.

I designed the request builder, response viewer, history, environments, and collections, then mapped the supporting flows for collaboration, test suites, mock servers, and CI/CD integration. The work used Figma and Cursor around a React and TypeScript platform.

The result was a browser-based interface that puts routine API work and advanced tools in the same place. This case is about the product and UX scope, not a claim that I built every backend feature or delivered a measured speed or cost gain.

If you are building a developer tool, message me with the workflow that feels harder than it should.
