STRATEGY
Designing a fast, mobile-first POS for restaurants and retail
SOLUTION
A mobile POS tailored for speed, usability, and compliance
I led the design end-to-end: from research and discovery to prototyping, validation, and handoff.
Key deliverables included:
Fast order flows → sales completed in just a few taps for both attendants and customers.
Auto-service mode → designed flows for kiosks/self-service ordering.
Modifiers & add-ons → flexible options for restaurant scenarios (extras, portions, notes).
Market flows → product list, quick search, and checkout optimized for retail.
Design system → scalable components supporting Android smart POS and tablets.
Compliance → flows designed around NFC-e fiscal requirements.
INSIGHTS
What we learned and achieved along the way
A design system ensures scalability
By creating a mobile-first design system, the product could evolve without fragmenting experiences across devices.
📊 Result: Improved collaboration with engineering and consistent rollouts across new device types.
Usability depends on device constraints
Smart POS devices had limited screen sizes, forcing us to design adaptive layouts. Optimizing for fewest taps possible became the central usability principle.
📊 Result: Seamless experience across different Android POS devices and tablets.
Auto-service expands efficiency
Designing self-service flows allowed restaurants to reduce pressure on attendants while giving customers autonomy.
📊 Result: Increased order accuracy and better distribution of operational load in restaurants.
