How I work

  1. 01

    Understand

    I cross-check user feedback with the needs of the product and the team.

  2. 02

    Decide

    I present journeys and mockups to the team, and I run FigJam workshops to prioritise.

    Variants explored with AI

  3. 03

    Build

    I prototype in Figma with the design system and the RGAA rules, then I follow implementation with the team.

    Prototypes, components and copy, faster

  4. 04

    Test

    I prepare test scenarios, then adjust the interfaces with feedback from users and the team.

With AI

  • A clear frame. I give AI the project rules: UX principles, design system, brand guidelines and tone of voice.
  • Producing faster. Variants, prototypes, components and interface copy, produced faster.
  • Staying in control. I compare the proposals and validate each version. Design decisions stay mine.
