My role Product and UX design

Responsive rules, workflows, handoff, and release review

Product Volanté POS

Restaurant order entry and service

Period 2023 to 2026

Work with design, product, engineering, and quality assurance

Scale 1,064 active POS terminals

Plus 84 active Cloud POS devices on September 14, 2026

Product at scale

## The shared POS system reached production and now supports a large active footprint.

1,064 Active POS terminals

84 Active Cloud POS devices

17,773,950 POS transactions

50.4% Of Volanté transaction volume

Volanté Product Specialist data from January 1 to September 14, 2026. The active footprint covers 422 live locations.

Project value

## Make fast restaurant work stay clear across screens, modes, and input devices.

### What the design needed to achieve

- ✓

Scale type, spacing, popups, and controls across three terminal sizes.

- ✓

Use one keyboard and keypad across login, search, payment, and approval.

- ✓

Organize each workflow around its ticket, states, behavior, and prototype.

Problem

### One product serves many tasks.

Order entry, search, payment, approval, customer accounts, printing, and service modes share one system.

Risk

### Every exception costs time.

Different layouts and input behavior slow staff during busy service and create more training work.

Direction

### Turn patterns into a system.

Responsive guidance and shared components reduce repeated decisions across product and engineering.

Design decisions

## Build reusable rules before adjusting individual screens.

01

### Start from real terminal sizes

Responsive foundation

The 26-page responsive file covers 1366 by 768, 1366 by 1024, and 1024 by 768 terminals.

Intended impact

Each layout decision has a clear reference size and manual device check.

02

### Research search behavior

Pattern study

A 142-participant placement study guided search position, button behavior, and suggestions.

Intended impact

Staff find search where they expect it and understand how results will respond.

03

### Share one keyboard

Common input

The Bar Tabs keyboard became the shared POS input for search, cash payment, manager override, and login in GA13.

Intended impact

Staff reuse the same input pattern across devices and tasks.

04

### Design for physical inputs

Device behavior

Touch, keyboards, scanners, cards, drawers, printers, scales, and payment devices all need clear ownership and recovery.

Intended impact

Disconnected, delayed, duplicate, and retry states become part of the workflow.

Product proof

## The design system grew from guidelines into shipped platform patterns.

Responsive system

### 2,508 frames

The 26-page guidelines cover sizes, gutters, popups, keyboards, keypads, and shared behavior.

Workflow authority

### 6,474 frames

The 36-page Quick Menu file holds ticket-based work across orders, customers, transactions, discounts, gift cards, and printing.

Released entry point

### Login and home

The Bar Tabs redesign became the POS login and home across service modes in February 2026.

Result

## The shared system reached production and now supports a large active footprint.

Released

### GA13 keyboard

One responsive keyboard replaced the legacy pattern across major POS input tasks.

Responsive coverage

### Three terminal sizes

The released guidance covers 1366 by 768, 1366 by 1024, and 1024 by 768 terminals.

Research

### 142 participants

The placement study guided search position, button behavior, and suggestions.
