Hi, I'm Leonnel

I’m a 28-year-old game programming student, currently in my 3rd year at Creajeux, a local university in Nîmes, south of France. Before pursuing my passion for game development, I worked in event organization and human resources while living in Montreal, Canada.

I see myself as a dedicated problem solver, always looking for new learning opportunities and ways to improve/sharpen my skills. I enjoy crafting games that not only feel great to play but are also built with clean, well-organized code. I thrive on tackling complex challenges, sometimes maybe too much, as I can get deeply absorbed until I find the perfect solution.
