UX UI Designer

A disagreement about an interface is rarely settled by argument: everyone judges by their own habits, which are not those of the users. The UX UI designer's work replaces these debates of opinion with observation. Five representative people in front of a prototype reveal most usability problems within an hour, and they are often different from those anticipated in meetings. Once the structure has been validated on that basis, applying the visual identity becomes a quick, low-risk step.

How we work

What we do

The work starts with the data available: conversion statistics, session recordings, feedback from customer service. These sources reveal the real points of friction, then the mock-ups propose solutions that are tested before being developed.

  1. 1

    Research and analysis

    Study of statistics, session recordings and user feedback to identify real points of friction.

  2. 2

    Information architecture

    Content organised according to the user's logic rather than your internal structure.

  3. 3

    Wireframes

    Greyscale mock-ups to validate the structure without being distracted by aesthetics.

  4. 4

    Prototype and user testing

    Clickable prototype tested with five representative people, with a report on the problems observed.

  5. 5

    Final design and components

    Application of the visual identity and creation of a reusable design system.

Expertise FAQ

UX deals with the journey and the logic, UI with the appearance. A serious project starts with UX: a beautiful screen on a confusing journey does not convert.

Yes: it is an established finding in usability research that five representative users reveal most of the major problems.

Absolutely, and it is often the best value for money: reorganising a form or simplifying a funnel improves conversions without touching the identity.

Yes: Figma mock-ups, specifications, components and documented interactive states.

By comparing before and after on specific indicators: form completion, cart abandonment, number of enquiries.
