Sophie Coste

UX/UI designer since 2019, I createuseful, intuitive, and efficient interfaces**, aligned with **measurable business objectives**. My approach combines **user research**, **data analysis**, and **continuous optimization**. Accustomed to **high-traffic environmentsandlarge-scale design**, particularly at **Adeo / Leroy Merlin**, **Mondial Relay**, and **Decathlon**, I design each journey with a performance-oriented vision: **improving conversion rates**, **reducing friction**, **direct impact on product KPIs**. Coming from a large group, I developed a **test & learnculture:rapid prototyping**, **user testing**, **A/B testing**, **data-driven iterations**. Every design decision is **justified, measured, and optimized**. A former stylist, I combine **graphic excellenceand **product efficiency**: detail becomes a lever for **understanding**, **credibility**, and **performance**. Based in Aix-en-Provence, I am looking for a **fixed-term or permanent contract within a product team**, where design is a **strategic performance lever**.
