A modular wallet

This banking wallet is a module, designed to plug into a banking app and grow with it.

At Worldline, my role: clarify the journeys, test them, and deliver design ready to industrialize.

Map the ground

Before we draw, we map.

Competition, , scope. We align the team on the same frame.

Then we move forward.

Framing

Sketch the journeys

of key : activation, payment, settings. Product, tech and design align on the same path.

If the journey holds here, it will hold later.

Make it tangible

Scenarios. Clickable .

The idea becomes something you can hold. We spot before writing production code.

Face reality

First round of user tests.

We watch. We record. We note what blocks, what surprises, what just works.

Hypotheses meet the field.

Tests in real conditions

Listen, adjust

Feedback on the feedback.

Before: what stuck. After: what we fixed.

New prototypes. New tests. The product tightens.

Before
After

Industrialize

migration. One base adaptable to several brands.

Figma specs for developers, then the key screens: wallet, activity, contactless payment, settings.

Design no longer stops at the .

Today

The frame is set, journeys are validated, are documented.

What I bring to this kind of brief: a clear method (frame, prototype, test, iterate), a product/tech culture, and care for industrializing without losing the user.
