About Noémie

🚀 +4 years of experience in mobile applications, SaaS tools, and e-learning projects.

Many applications lose their users within the first few days.
Not because the product is bad. But because no one has taken the time to design a journey that truly shows why it's worth staying.

That's where I come in.

I help product teams design mobile applications that engage their users from the start, by combining UX audit, interface design, and user testing.
I help product teams design mobile applications and e-learning experiences that engage their users from the start, by combining UX audit, work on onboarding, user journeys, and interface design.

🎯 For whom?
  • Startups and publishers launching or revamping a mobile application
  • Training managers and e-learning teams who want an app their learners actually use
  • Founders who have great content but an app that doesn't convert, without knowing exactly where it's faltering

⚙️ My process
  • Audit of the existing application and identification of friction points in the user journey
  • Design of key user journeys from the first screen to the first success
  • Interface design (wireframes, Figma mockups, interactive prototypes)
  • User testing and iterations
  • Delivery with documentation for the technical team

🛠️ What I deliver
  • Audit report with prioritized recommendations
  • High-fidelity UI mockups on Figma
  • Interactive prototype ready for testing
  • Design system

💡 The easiest way to start: a UX audit of your current application.
You'll leave with a clear diagnosis and concrete actions, with no commitment to continue.

📍 Based in Nantes.

    UX/UI Designer & Co-founder · E-learning & Education Project
    EDUCATION AND E-LEARNING
    July 2024 - January 2026 (1 year and 6 months)
    Nantes, France
    Hémolia was born from a final project that was extended out of conviction. With a partner, we conducted in-depth research around childhood, learning, and education: interviews with parents, teachers, and child development professionals, field observations, and tests with families.

    This research led us to design several projects around emotional education, including a card game for families to facilitate communication about emotions. Each project was tested and iterated with real users, parents, and children.

    This project has deeply trained me in the specifics of designing for children, the importance of inclusive and participatory design, and the rigor required to create e-learning and educational tools that truly work.

  • Freelance
    UX/UI Designer and Facilitator
    CONSULTING AND AUDITS
    April 2025 - January 2026 (9 months)
    Tours, France
    Period of exploration and skill development in freelance UX/UI Design. I worked on several mobile application and digital interface design projects, from ideation to Figma prototyping. I worked to understand real needs, listen to users, and find the right balance between their expectations, technical constraints, and project objectives.

    I also developed an approach centered around facilitation workshops and collective intelligence applied to design, to co-build solutions with product teams and end-users.
    Because a good product is not built alone: it is born from collaboration, listening, and collective intelligence.
