Back to original languageAbout Corentin
Frontend Developer specialized in React / TypeScript, with strong expertise in UX/UI, I design interfaces that are performant, intuitive, and user-oriented.
I have been developing since I was 15 years old (over 15 years of experience), with a background built on demanding environments: telecommunications, banking, and cybersecurity. These contexts have allowed me to acquire real rigor in the quality, security, and reliability of applications.
My approach goes beyond simple development: I pay particular attention to the user experience, the readability of interfaces, and the efficiency of user flows. My goal is to create products that are not only functional but also pleasant and effective to use.
💡 What I can bring you:
Design of modern and ergonomic interfaces
Clean, maintainable, and scalable React / TypeScript development
UX/UI improvement of existing products
Integration of complex dashboards (data, security, monitoring)
Smooth collaboration with product, design, and backend teams
In parallel, I contribute to volunteer projects around video games, which allows me to stay creative and constantly aware of new technologies.
Autonomous, involved, and results-oriented, I quickly adapt to your challenges to deliver effective and sustainable solutions.
