Challenge

Rigid brand guidelines created visual and accessibility issues across the app.

Approach

Create a scalable UI system while improving usability without breaking the new brand.

Outcome

A redesigned experience with improved hierarchy, accessibility and consistency.

Up Sí Vale had recently refreshed its brand, but its digital products still reflected an outdated transactional experience.

Old design
  • — Dense layout
  • — Weak hierarchy
  • — Low contrast
  • — Inconsistent icons

The redesign was not about making the interface prettier.

Design Principles

Accessibility first

Consistency

Progressive disclosure

Reduce cognitive load

Recognition over recall

Clear visual hierarchy

Accessibility

Instead of blindly following the new branding, we documented digital accessibility best practices and collaborated with stakeholders to adapt colors, contrast and interaction states while preserving the visual identity.

Every component was documented and standardized inputs, buttons, and interactive states.

We redesigned first-time use into a guided experience, introducing information progressively instead of overwhelming users with complex registration flows.

The home had different versions depending on the product card the employees had.

After

The home evolved from a balance viewer into a personalized dashboard with quick actions, promotions and contextual information.

The Promotions section was designed for discovery through categories, search and personalized content.

  • Simpler navigation.

Product

  • More scalable interface.
  • Reusable patterns.
  • Faster feature development.

Design

  • Foundation for future features.
  • Consistent language.

Good interface design is not decoration.

It is the discipline of making complexity feel effortless. Sometimes the greatest design achievement is invisible to users because everything simply works.
