The short version

Context
The fintech market in Brazil is notoriously rigorous: dominated by traditional banks and contested by digital-native neobanks. Even with so many options, people still navigate convoluted interfaces full of hidden fees and confusing requirements.
Problem
Mapping the main frustrations showed a clear pattern: hidden fees (78%), cluttered dashboards (65%) and excessive bureaucratic clicks (55%). People wanted control and transparency, not more products competing for their attention.
What I did
Magnum SCD was conceived at the intersection of transparent financial agility and emotional connection. Its promise, “Here your passion is worth more”, called for design sprints to unpack the industry baseline, define the product foundation, prototype fast and ship.
Impact
The MVP focused on four journeys, with one problem per screen and the essentials always one tap away.

Market research across Nubank, Banco Inter, C6 Bank and Mercado Pago compared value propositions, UX patterns, frictions and support. Sketching and whiteboard iterations consolidated the MVP into four critical journeys.

Seamless onboarding in under three minutes with OCR and facial biometrics, a smart dashboard that groups expenses automatically, instant transfers on a Pix-first architecture, and benefits connected to the user’s passions.

Pagar: Pix, barcode, automatic debit, DDA, top-up, taxes and vehicle fees
The credit card: current bill, limit and transactions by day
Extrato: balance, movements and scheduled payments by day
The splash screen and the first onboarding step
“Here your passion is worth more.”

Design

Mid-fidelity wireframes came first, then a high-fidelity UI with a bold identity and a clear hierarchy. The goal was to remove cognitive noise: no redundant menus, no excessive gradients, just clear transactional flows.

The same patterns carry over to internet banking, so a customer moving from phone to desktop finds the statement, Pix and payments exactly where they expect them.

What I learned

Friction makes better interfaces: every bureaucratic click we removed came from listening to where people gave up.

First impressions drive adoption, and design thinking aligned a fast-moving team around four journeys instead of forty features.
