About Jimmy

Freelance UX/UI Designer, I assist product teams in designing clear, effective, and consistent interfaces.

After 5 years of study and a 2-year apprenticeship in a B2B environment related to mobility, transport, and payment services, I worked on concrete products (portals, dashboards, mobile journeys, etc.).
I launched myself as a freelancer to explore other fields and discover new product contexts.

What I can do for you:
  • UX Audit + Recommendations
  • UI Mockups (web / mobile)
  • Redesign of screens, journeys, and flows
  • UI Kit (components, styles, guidelines)
  • Figma Prototyping (interactions, testing, handoff)
Looking forward to collaborating with you!
  • French

    Native or bilingual

Experience

  • Hoxidis

    TECH
    January 2026 - Today (5 months)
    Lyon, France
    As a freelance UX/UI Designer, I specialize in designing interfaces for software and mobile applications, with a simple goal: to create clear, consistent, and easy-to-use products.

    My daily work involves supporting projects from end to end, transforming a business or user need into structured journeys, and then into directly usable screens. I work on both new creations and redesigns, with particular attention to readability, visual hierarchy, and the overall consistency of the product.

    I work on various topics, with a natural inclination for domains where the experience must be reliable and fluid: transport, mobility, banking/payment, but also more service-oriented sectors like restaurants.

    December 2023 - September 2025 (1 year and 9 months)
    Lyon, France
    For 2 years during my apprenticeship at Worldline, I worked in a B2B environment at the intersection of mobility, transport, and payment services, within product teams.

    My daily work involved contributing to making business products clearer, more consistent, and easier to use, by working on materials and interfaces related to user journeys. I notably participated in the improvement and harmonization of deliverables around concrete products: administrator portals, dashboards, mobile journeys, as well as UI kit elements to enhance consistency and scalability.

    This experience taught me to work with real constraints (B2B, multi-stakeholder, clarity and reliability challenges), to collaborate with different profiles (product, tech, marketing), and to produce directly usable deliverables (mockups, prototypes, recommendations).
