Freelancer profile translated to English.
Back to original languageAbout Julien
For 19 years, I have been supporting organizations of different sizes and sectors on complex issues with high business, technical, or regulatory stakes.
I have worked in regulated fintech, banking and institutions, retail and e-commerce, industry, mobility and energy, as well as in media, SaaS, education, health, and social impact. This diversity allows me to quickly identify what constitutes a structuring problem and what is merely a superficial symptom.
On a long-term assignment, my role is to set the right framework, clarify trade-offs, align teams, and transform this vision into concrete deliverables. I work seamlessly between strategy and craft, from framing and user research to user journeys, interfaces, Figma prototypes, and exchanges with delivery teams.
I also intervene occasionally for short missions: UX audit, targeted or global UX and UI redesign, Figma prototype, framing of a blocked project.
Pure craft, delivered quickly, with the hindsight of a senior.

They are its framework. I work on complex and structuring issues with an approach focused on clarity, robustness, and sustainable alignment between design, product, technology, and compliance.
