About me
Intro
UX/UI Designer | 15+ years in Graphic Design | Based in France With 15+ years of experience in graphic design — across medical, real estate, and food industries — I approach UX with one consistent goal: creating experiences that deliver measurable results. What drew me to UX is precisely that connection between design and real impact. During a full website redesign, I reorganized a complex product catalog into an intuitive category structure, and led the platform migration. The result: +155% revenue growth between 2019 and 2024, compared to +69% for the French market average (source: Fevad). Today, I'm fully focused on UX Design — combining my visual craft with user research, prototyping, and usability testing. I've completed hands-on training in product design (Le Laptop, Paris) and hold the Google UX Design Certificate. I'm looking for a UX/UI design opportunity in France to collaborate with a product team passionate about crafting meaningful digital experiences.

Through the Google UX Design Certificate on Coursera, I’m gaining hands-on experience in the foundations of UX design, including user research, wireframing, prototyping, and usability testing. This program is helping me develop a user-centered mindset and practical design skills to create intuitive, accessible, and effective digital experiences. Combining my graphic design background with my growing UX skills, I’m excited to build digital products that are both visually appealing and functionally seamless.
