Jorge Rubiano
Huge, Colombia
Hi! I'm Jorge Rubiano, a passionate developer with several years of experience in the programming world. Throughout my career, I've discovered that one of the best ways to learn and teach is through personal projects, and in my case, games have been my greatest source of inspiration. I love immersing myself in game development because not only are they fun, but they also provide a valuable opportunity to learn new technologies and concepts. Each game I create challenges me to explore and master emerging technologies, from frameworks to libraries, and even design concepts and game logic.
