Description

👋 Hello !

Product Designer with 12 years of experience (8 years freelance, 4 years as an employee), I have worked for renowned companies such as Cheerz, KissKissBankBank, BlaBlaCar, Scaleway, and JobTeaser.

What I do:

Product Design UI & UX

From ideation to delivery, I support product teams at every stage: ideation workshops, persona creation, user interviews, user story mapping. I work closely with Product Managers to define needs, structure user journeys (user flows, global views), and produce consistent interfaces — thereby facilitating dialogue with developers.

Design System

I designed and implemented the complete cross-platform foundation at BlaBlaCar: color tokenization, typography, spacing, and more. Solid experience that allows me today to work on creating a design system from scratch as well as evolving it.

Advanced Prototyping

I create high-fidelity prototypes in Figma, and I push the boundaries further with Figma Make and Claude Code to generate front-end code directly from mockups — a real gain for rapid testing and bridging design and development.

Tools:

Figma · Figma Make · Jira · Notion · Sketch · Adobe Suite (Ps, Ai, Id)

Basics in HTML5/CSS3 and JavaScript — useful for effective collaboration with dev teams and bringing functional prototypes to life.
