user-interfaces

Builds and reviews screens and components on any front-end stack, including web, mobile and desktop. Use whenever someone creates or changes a page, component, form, table, modal or client-side state, or a UI bug appears, even if they only say "armame esta pantalla" or "el formulario no anda". Covers loading, empty and error states, accessibility, responsive layout, forms, front-end performance and checking the result in a real browser or simulator. For endpoints behind the UI use api-design; for visual brand design and mockups use a design tool.
