I’m taking a new e-commerce idea to market and need a polished, conversion-friendly UI/UX for the mobile app only. Wireframes for the main flows are ready; what I now require is a designer who can refine the experience, create a compelling visual language, and hand over assets the dev team can drop straight into Xcode and Android Studio. Please show me relevant past work—live apps or interactive prototypes are even better—so I can see how you tackle onboarding, product discovery, checkout, and micro-interactions. Deliverables I expect: • Low- to high-fidelity mock-ups for all core screens • Clickable prototype (Figma, TeleportHQ, Sketch or Adobe XD—your choice) covering the full purchase flow • Design system (color, typography, iconography, UI components) packaged with exportable assets and style guide PDF My acceptance criteria are straightforward: every user story in the current wireframes must be covered, the design must follow current iOS and Android guidelines, and the prototype must pass a quick hallway usability test I’ll run with five target customers. If this aligns with your experience, share the best examples from your portfolio and a short note on how you normally move from concept to final hand-off.
