As the UI/UX Designer, I owned the design process from information architecture and user flows through wireframes and visual design. I partnered with the Product Owner, stakeholders, and development team to define requirements, shape the experience, and present design solutions for review and alignment.
Overview/ Users
Chevron wanted to increase engagement among heavy convenience-store users—frequent, loyal customers who often viewed ExtraMile as a secondary option to competitors such as 7-Eleven. The goal was to make ExtraMile part of their daily routine by creating a more rewarding and convenient experience.
The ExtraMile mobile app was designed to strengthen customer engagement and connect digital and in-store experiences. I contributed to Wave 1, which did not include mobile payment.
Key capabilities included:
Loyalty program enrollment and access
Location-based in-store promotions
Store and product discovery
Rewards tracking
Customer feedback
Multiple language options
Challenge
The client required a consistent experience across iOS and Android. Working within a tight timeline, I streamlined the design process using NinjaMock for rapid wireframing and InVision for prototyping, collaboration, and design reviews.

Information Architect Problems
During the design process, I encountered a platform-specific navigation challenge. The original concept placed the primary navigation at the bottom of the screen to create a modern, accessible experience. However, Android’s system navigation created potential conflicts with this approach.
While the client initially wanted a consistent experience across both platforms, we agreed to follow platform-specific design conventions. For Android, we used a collapsible navigation menu, while the iOS experience retained bottom navigation.

Visual Design
Our team led the visual design for the initial phase of the project. During Wave 2, a creative agency joined the effort, contributing promotional and marketing assets.
Results
The project successfully launched the following year on both Google Play and the Apple App Store, achieving a 4+ star rating and more than 10,000 downloads.
