About Julia

Product Designer UX/UI, from user research to interfaces

I support product teams on SaaS interfaces and complex workflows: understanding real usage, simplifying what's blocking, and delivering development-ready screens.

Graduated with a Master's in UX/CX from EFREI, I've worked on digital products at Air France and on business SaaS platforms, from the discovery phase to delivery.

Some results

+20% adoption on a feature after redesigning the user journey
Journey shortened by 10 clicks, by simplifying the sitemap and validation steps

What I work on

- UX Research: user interviews, journey mapping, identifying pain points
- Discovery & Scoping: ideation workshops, prioritizing features by value
- UI Design: wireframes, high-fidelity mockups, and prototypes
- Design System: structuring and documenting reusable components
- AI Feature Design: designing the experience around AI, when it intervenes, what it shows, what the user keeps under control

My way of working
I work in an agile manner, in direct contact with Product Managers and developers.
I deliver documented and usable interfaces, not just mockups.
