I naturally ask questions and try to understand people, problems and context before jumping into solutions.

I enjoy simplifying complex systems, workflows and information to create clearer experiences.

Delight is in the details

About

Hey

Hi, I’m Celine, a UX/UI Designer based in France and I work with teams that design B2B products, web applications, and business tools. I have a background in software development.

I’ve always enjoyed understanding how things work, and even more, understanding why they sometimes don’t.

I naturally ask a lot of questions, whether it’s about users, products or the people behind them. I enjoy connecting the dots, creating clarity and helping teams move forward together.

My development background helps me understand technical constraints and and facilitate communication between design, product, and engineering teams.

What I enjoy most is solving difficult problems and turning complexity into experiences that feel simple and useful.

Outside of work, I enjoy traveling, hiking, practicing yoga, and spending time with my family.
