Designing for Scale: A Flexible, White-Labeled Credit Card App for Global Financial Brands

‍

Story

At Fiserv, the challenge wasn’t just designing a credit card app — it was creating a white-label platform that could be deployed across dozens of banks and financial brands worldwide. Each client needed unique branding, but the core workflows had to remain consistent, fast, and intuitive for end users.

As Lead Product Designer, I developed a modular, scalable system capable of adapting to different brands while supporting a seamless onboarding and digital provisioning experience. I delivered over 300 high-fidelity screens across mobile and web, built a comprehensive design library, and helped transform the product into a scalable, sellable solution.

The result? Faster client launches, fewer customization errors, and a polished UX that made complex rollouts feel effortless — for clients and their users.
