About Léa

Hello 👋

Product Designer (UX/UI & Web) based in Paris, I help startups, SMEs, and agencies in designing structured, clear, and high-performing digital products and websites.

I work from strategic thinking to interface design, with an approach that connects structure, user experience, and interface quality.

How can I help you?

PRODUCT DESIGN (UX & UI)

I design products by thinking about logic before visuals.

This includes:
  • Needs research and analysis
  • User journey definition
  • User flows and information architecture
  • Functional structuring (SaaS, platforms, internal tools)
  • Wireframes and prototyping
  • User testing
  • Web and mobile interface design
  • Digital art direction
  • Design systems & UI kits
  • Responsive design and micro-interactions
UX and UI are not two separate steps: structure and interface must work together.

WEB DESIGN

I design showcase and business websites with the same standard as a product:
  • Content structuring
  • Clear hierarchy
  • Conversion-oriented journeys
  • SaaS landing pages
  • WordPress / no-code integration
  • High-performing and maintainable interfaces
A website is not just a showcase, it's a tool.

I also have a sensitivity to visual identity, which allows me to create interfaces consistent with brand image while remaining focused on user experience.

**My goal**: to design digital experiences that are understandable, credible, and effective.

    Linkeez is a digital business card SaaS solution for local professionals, designed to centralize their information and facilitate the generation of business opportunities.

    Context
    Product developed from scratch: from the initial idea to the MVP, then to the first improvement phases.

    Small team: one executive, one developer, and myself as the sole Product Designer.

    Role
    As the sole designer, I actively participated in the functional structuring of the product and strategic feature choices.

    My role was not limited to interface design: I contributed to defining the business logic, activation journeys, and consistency between the product, freemium model, and positioning.

    Missions
    • Co-creation of features with the executive
    • Definition of user flows and information architecture
    • Complete structuring of onboarding and the “first value moment”
    • User dashboard design
    • Definition of the freemium logic and subscription journeys
    • Digital card management and configuration
    • Design of analytics modules
    • E-commerce journey structuring
    • Complete design of the desktop SaaS interface
    • Design and adaptation of the mobile application
    • Design of the marketing website (offer hierarchy, conversion logic)
    • Interactive prototyping and user testing

    Results
    • Measurable improvement in journeys following user tests
    • Simplification of complex features
    • Better understanding of onboarding
    • Facilitated activation from the first steps
    • Positive feedback on dashboard clarity
    • Rapid MVP validation with targeted iterations
    • Enhanced consistency between product, freemium model, and marketing site
