Cashi, a fintech digital wallet app developed by Walmart Mexico, offers users the ultimate in convenience for bill payments, top-ups, and cashback at affiliated stores nationwide. With an impressive user base of nearly 6 million, Cashi is poised for further expansion into banking services and payments at non-Walmart outlets, promising exponential growth. Recognizing the need for a visual overhaul to accommodate these new services and maintain a competitive edge, Cashi embarked on a redesign journey.

As a product designer, I played a pivotal role in this transformation, contributing to the creation of a comprehensive design system and detailed documentation. I also streamlined our workflow by introducing Design Operations files. Leading initiatives related to bill payments, I laid the groundwork for Cashi's Marketplace, particularly in its inaugural phase focusing on gaming.

Our team meticulously crafted a design system, a collection of reusable components defined by rigorous standards. These components serve as the building blocks for robust, user-friendly, and consistent products across both design and engineering.

In our quest for excellence, we analyzed over 20 financial apps from Mexico and worldwide. This deep dive informed the creation of a new design system from scratch.
Over 13 weeks, we generated more than 30 components with over 2000 variants, each meticulously documented with definitions, usages, variants, and engineering tokens.

Adapting to the majority of our users on Android devices (92%), our design system was tailored to meet their needs. The advantages of this system are profound: heightened efficiency, unwavering consistency, and a significant reduction in costs. This project not only refreshed Cashi's visual identity but also positioned it as a leader in the ever-evolving landscape of fintech.

As a testament to our success, we achieved the number 1 position in the most downloaded financial apps in the Mexican market in both Google Play and the App Store in November 2023.
