My Role
As Conceptual Designer, I defined the end-to-end UI system for the Advance Store Mobile hand scanner — a floor-based checkout experience that eliminates POS counter dependency and brings transaction capability directly to the retail floor.
Delivered under a 48-hour turnaround — a complete design system and low-fidelity prototype for direct client presentation. Speed without quality compromise.
Design Challenges
Three simultaneous constraints defined every design decision: legacy hardware (iPod), Native Basis UI components for React Native and Vue Native compatibility, and a White Label Solution architecture adaptable to any retail brand. No decision could satisfy one constraint at the expense of the others.
48hr Turnaround
Under constraint, clarity becomes the design principle. I stripped the interface to its essentials — every element earned its place. The result: a clean, dual-role UI that served the employee scanning items and the customer completing payment without requiring separate screens for each context.
Success
Post-review, the flow was refined: final payment steps moved to the customer-facing side, shortening the employee interaction significantly. Stakeholders approved and advanced the design to the next project phase. A 48-hour brief became the foundation for a real product direction — the clearest validation of constraint-driven design.
Approved design — advanced to next project phase.
