About Théophile

👋 Nice to meet you!

More than just a developer, I am your technical partner to bring your Web and Mobile projects to life.

Passionate about beautiful interfaces and clean code, I help companies create fluid user experiences. My dual expertise allows me to have a global vision of your product:

💻 Web: Fast and optimized websites (SEO) with Next.js and React.js.

📱 Mobile: High-performance native applications on iOS and Android thanks to Flutter.

As a freelancer, I prioritize transparency, responsiveness, and good humor. My goal? That you are as proud of the final result as I am of my code.

Let's discuss your project over a coffee (virtual or real)!
