Computer science student
Hi, my name is Johny Hsieh.
I’m a computer science student based in Diamond Bar, California. I build full-stack software, engineering projects, and educational technology using Python, JavaScript, Java, React, and Flask. I also apply AI and machine learning tools to practical projects. Through award-winning technical projects, leadership, and hands-on problem-solving, I enjoy turning ideas into useful tools. At Code Ninjas, I teach programming and help students build confidence through coding projects.
