Phase 2 DESIGN UX/UI - Joiner-SASU en cours de création

Reviewed on 1/30/2026

I had the pleasure of working with Mylène on phase 2 of the UX/UI design for my project, and I am very satisfied with the collaboration. Mylène quickly understood the project's challenges, technical constraints, and long-term vision. Her work is structured, relevant, and user-oriented, with a real focus on user journeys, ergonomics, and overall interface consistency. The delivered mockups are clear, modern, and usable, which greatly facilitates the development phase. She is also very professional in her interactions: responsive, attentive, proactive, and always constructive. I highly recommend Mylène for any project requiring a serious, thoughtful, and high-quality UX/UI approach. This is a collaboration I would not hesitate to repeat.
