About Me

Curious by nature,
Developer by passion,
Aviation lover.

I'm a 15-year-old student & developer based in France. My journey started with simple curiosity—copying websites to understand how they work—and quickly evolved into a genuine passion for building software.

From command-line tools to full-stack web applications, I love the process of turning problems into solutions. I also have a deep love for aviation ✈️. Whether it's flight simulation or understanding the mechanics of flight, the sky has always been a source of inspiration for me.

Beyond the code and the cockpit, I'm a handball player (pivot position). It’s taught me that coordination, strategy, and teamwork are just as important on the court as they are in a development team. I believe in clean code, continuous learning, and building things that matter.
