Hey

Hey

I'm Celine, a Product Designer based in France, with a background in software development and UX/UI web design.

As a developer, I discovered what a product truly is: how to enhance it by collaborating with clients on their business needs and by getting closer to users to understand their needs and address them. I’ve always enjoyed thinking about the product as a whole, and that’s what led me to specialize in UX/UI design.

I’ve worked on international projects in fast-paced, startup-style teams, and later as a freelance designer, where I built Webflow websites from scratch using the full UX process. I've continued to grow through several bootcamps and hands-on projects.

Today, Product Design brings together everything I love: imagining, designing, and crafting intuitive and useful experiences. I enjoy working with teams, sharing ideas, and learning together. I’m curious and comfortable with technical teams thanks to my dev background.
