 High-fidelity UI screens

·       Polished, production work across web and/or mobile. We''re evaluating visual craft, typographic and spacing decisions, and consistency across screens, not just wireframes or flows.

 Prototypes

·       At least one interactive prototype demonstrating transitions, states, or interaction logic relevant to the project context.

 Iteration examples

·       Work showing how you responded to feedback or constraints from a lead or stakeholder. We want evidence of collaborative execution, not just independent creative direction.
