A financial institution needed to launch a competitive digital account from scratch within a tight 7-month window. With no existing product vision or design system, the challenge was to define a complete end-to-end experience—from onboarding to core banking—that felt joyful and minimalist in a saturated market.
Market Adoption: 27% boost in user adoption within the first three months post-launch.
Scalability: Delivered a comprehensive Design System and UI Kit, enabling the team to ship new features with 100% consistency.
Validation: 0% high-difficulty rating in final usability testing for core journeys (Pix and payments).
The Strategic Journey
1
Strategic Foundation
As the Lead Product Designer, I kicked off the project with in-person co-creation workshops. We aligned stakeholders on a "minimalist yet joyful" vision, transforming complex banking requirements into a lightweight, user-centric product strategy.
2
Research & MVP
Working with an external research team, I translated benchmarks and user trends into architectural hypotheses. We moved fast: wireframing, testing, and iterating until we defined an MVP that focused on the "Spy Mode"—allowing users to explore benefits before even committing to a full signup.

Modular Design System
To move at the speed of a startup, I built a robust design system in parallel with the product. By creating a library of reusable components (navigation, modals, numeric boards), we accelerated the development of over 15+ complex banking screens while maintaining a premium feel.
4
Iterative Delivery
The second phase shifted to remote collaboration for deep-dive functionalities. I led the design of high-stakes flows like Pix (instant payments), transfers, and card management, using iterative testing cycles to catch errors and refine scenarios before the final hand-off to engineering.

Impact & Reflection
Building a bank from the ground up required a delicate balance between creative vision and technical constraints. This project proved that investing in design infrastructure early isn't just about aesthetics; it’s a business multiplier that secures user trust from day one.
