About Julien

Hello, I'm Julien đź‘‹

Passionate about digital, I started my career as an UX Designer before specializing in the creation and management of SEA and SEO campaigns. This expertise has been developed through my entrepreneurial projects and reinforced by in-depth training with a Google expert.

During my Data Driven Marketing studies, I learned to leverage data to drive effective marketing strategies and accurately measure their impact.

This dual profile, combining UX and Data Driven Marketing with expertise in SEO/SEA, allows me to design high-performing acquisition strategies. My goal: to combine optimal user experience with campaign optimization to maximize your results and achieve your growth objectives.
