Description

Flutter Developer with over 7 years of experience, complemented by several years in native Android. I have worked on international projects, notably in France, England, and Germany, on both early-stage products and applications with millions of users.

I notably evolved in a demanding Silicon Valley-type tech environment at Betclic, where code quality, scalability, and user experience are absolute priorities.

I design mobile, web, and desktop applications in Flutter, with particular attention to:

🧼 clean and maintainable code

⚡ optimal performance

🎨 polished and consistent design

👤 a resolutely user-centric approach
