Rang

QR Code Restaurant Ordering & Service Platform

PROJECT OVERVIEW

Rang is a web-based application that lets customers view the menu, place orders, message their server, and pay directly from their mobile device using a simple QR code scan. The goal was to reduce friction between customers and restaurant staff while eliminating the need for restaurants to purchase additional hardware.

THE CHALLENGE

In traditional restaurant service, customers often struggle to get a server’s attention when they need something - whether it’s a missing item, an additional order, or the check. This leads to wasted time for both customers and staff, slower table turns, and a less efficient dining experience. Restaurants also wanted a solution that wouldn’t require buying new equipment and would keep the existing payment process secure.

THE SOLUTION

Rang enables direct, real-time communication between customers and servers through their mobile devices. Customers can request assistance, add items to their order, or pay their bill without waiting for a server to physically come to the table. This significantly reduces unnecessary back-and-forth trips while improving service speed and table turnover. The platform is web-based, so restaurants incur no additional hardware costs, and payments continue through their existing secure systems.

MY ROLE

As Sr. UX Lead & Product Manager, I led the end-to-end design and product efforts for Rang. My responsibilities included:
- User research and competitive analysis
- Design strategy and information architecture
- Wireframing, prototyping, and design system creation
- Usability testing with both customers and restaurant staff
- Cross-functional collaboration with development and stakeholders
- Project management, documentation, and mentorship of junior designers

Tools used: Figma, Adobe XD, Jira, Lucidchart, Sketch, Balsamiq, Optimal Workshop, Photoshop, and Illustrator.

DISCOVERY & RESEARCH

I began by researching competitor solutions and conducting both qualitative and quantitative user research. I gathered feedback from restaurant owners, managers, and customers to understand pain points around service speed, communication, and payment flow.

Key deliverables included:
- User personas
- User journey scenarios
- Identified problems paired with proposed solutions

The research confirmed that both customers and restaurants wanted a simple, low-friction way to communicate without adding complexity or new hardware.


DESIGN APPROACH

I focused on creating an experience that feels effortless and intuitive, minimizing cognitive load for users in a busy restaurant environment. Core design principles applied:User-centered design - Built around real user needs and contexts
Clear, simple navigation - Easy to use even for first-time users
Minimalist aesthetic - Clean interface that doesn’t overwhelm
Responsive & accessible - Works seamlessly across all mobile devices
Consistent feedback - Clear confirmation for every action (ordering, messaging, payment)
Iterative refinement - Continuous improvement based on testing feedback

The design was intentionally kept simple so anyone could use it without instructions.Implementation & CollaborationI worked closely with development teams throughout the project to ensure designs were implemented accurately and efficiently. This involved regular alignment meetings, detailed design handoffs, and ongoing feedback loops.

As UX Lead and Product Manager, I also:
- Facilitated iterative design sessions based on stakeholder and user feedback
- Coordinated cross-functional collaboration between design, development, and business teams
- Managed project timelines, tracked progress, and communicated updates to stakeholders
- Organized usability testing with real customers and restaurant staff
- Developed the launch strategy and conducted post-launch analysis to identify areas for improvement

Through close collaboration and a strong focus on usability, we delivered a solution that improved service efficiency while remaining simple and secure for both customers and restaurants.
