About Marie

đź‘‹ Hello, I'm Marie, an UX/UI designer.

For several years, I've been supporting product, design, and innovation teams who are trying to answer a simple but essential question: "How can we create something that truly matters to our users?"
This is where I come in.

I quickly understood that intuition is not enough. What truly transforms a product are real-world uses: spontaneous gestures, silent frustrations.
This is why user research is at the heart of my practice: interviews, observations, tests, co-design workshops, focus groups… anything that helps understand the life behind the screen.

But understanding is only the first step.
I also enjoy giving shape to these insights.
Thanks to my UI sensibility, I create coherent, accessible, and embodied interfaces: wireframes, high-fidelity mockups, design systems… For me, UI is not just a visual layer; it's the concrete translation of what users have taught us.

I also place great importance on pedagogy and change management: explaining, sharing, aligning… especially when the results challenge internal habits. My goal is to help teams adopt the learnings and convert them into operational decisions.

My background in communication and digital marketing gives me a global vision of business challenges while remaining grounded in user needs. This allows me to play a natural bridging role between teams.

What I produce according to needs:

Personas, empathy maps, user journeys, UX audits, low/mid-fidelity wireframes, UI mockups, design systems, guidelines, operational summaries.

My tools:
Figma, Miro, Sketch, Adobe XD, Adobe Creative Suite, Canva.
With some basics in HTML & CSS to facilitate communication with tech teams.
