I start by understanding before producing. In B2B SaaS, the real problem is rarely the one I'm told upfront. So I spend time with users, product teams, and sometimes end clients before touching Figma. Design comes next: fast, iterative, shared early. I'm not attached to my mockups, what matters is that the product works for the people actually using it, not just the ones who ordered it. I deliver clean specs, maintainable design systems, and stay available during implementation. The best design that never ships is worth nothing.

I’ve fully integrated AI into my workflow, not to replace design thinking, but to move faster and explore further. I use it to iterate quickly on layouts, accelerate benchmarks and research, and build high-fidelity conditional prototypes that previously required tools like Axure.
To make this work properly, I structure my Figma files, variables, naming conventions and design systems to support AI-assisted dev integration and scalable collaboration. I use MCP servers to connect Figma and its design context directly to AI tools, creating a more fluid bridge between design and development.
I studied multimedia design at IUT Bourgogne, then completed a Master in Web Design at ECV Digital in Paris. Eight years later, I'm still driven by the same thing, making complex things feel simple. I've built products from scratch, reshaped existing ones, and worked across fintech, energy, HR tech, legal tech and cybersecurity.
What brought me here is a curiosity for technology and multimedia content that never switched off. Design is what happens when that curiosity meets people, it's the layer that makes technology make sense. That's why I also explore 3D modeling, motion and development as ways to keep thinking about products from the outside in.
