I have been a web frontend developer since 2014. And 🚀 freelance since Sept. 2022. After 1 year on a mission at Paprec, Nantes, I am currently looking for a mission for January in Nantes or Paris.
My tools include JavaScript and TypeScript with Angular, HTML and CSS, Ionic, Cordova, and PWAs. But I am also willing to discover new frameworks like Vue.js.

📐 Participate in architectural and technical choices
🔗 Supervise (and automate) code quality, adherence to best practices, and syntax consistency
⌨️ Solve the most complex technical problems and refactor existing code
💪🏼 Be proactive in proposing features, design, and ergonomics
