Fiserv needed a mobile experience that served both iOS and Android users without feeling like a compromise on either platform. The existing app had fragmented patterns, inconsistent navigation, and accessibility gaps that created friction for users managing sensitive financial data.

Lead Product Designer responsible for end-to-end mobile experience. I defined the design system, created high-fidelity prototypes, and collaborated with engineering to ensure platform-appropriate implementation.

Created a unified design system that respects platform conventions while maintaining brand consistency. Established interaction patterns that feel native on each platform, streamlined navigation architecture, and ensured WCAG 2.1 AA compliance throughout.

Financial apps live or die on trust. The strategy was to eliminate friction and inconsistency—anything that makes users pause and wonder if something's wrong.

Cross-platform design isn't about making things identical—it's about making the experience feel equally considered on both platforms.

Expand design system to tablet breakpoints; implement dark mode; add biometric authentication patterns.
