About Léa

Hi, I'm Léa 👋

Designer for over 6 years, I've supported teams, startups, and major brands, from the whiteboard idea to the final online product.

My daily life is about understanding users, structuring the experience, and translating all of that into clear, beautiful, and effective interfaces. I enjoy projects where design plays a real role: not just "making it pretty," but designing to convince, guide, and retain.

Currently in a permanent position, I'm opening up some freelance slots for short, targeted missions, with clients who want a truly expert eye, not a service provider who just gets it done.

What I can do for you:

🔍 Audit your website or landing page and tell you exactly what's hindering your conversions
🚀 Design an UX + UI landing page from A to Z, optimized for conversion
🎨 Create or redesign your visual identity so it truly reflects who you are

What you get by working with me:
An involved person who understands your business challenges, communicates clearly, and delivers clean, documented files.

Clients I've worked with: Bouygues Immobilier, EDF ENR, SPA, Emmaüs, Amnesty International, EM Lyon, Shiptify…
