About

Hello! I'm Jung Ki Lee, a recent graduate from the University of Illinois at Urbana-Champaign with a Bachelor's degree in Computer Engineering. Currently, I am working as a Tech Manager at Superplanet, where I manage the infrastructure for multiple mobile game projects. My journey in technology has been diverse, ranging from software development to machine learning and computer vision. Originally from South Korea, I have also lived in Germany and Uzbekistan. My current interests lie in autonomous systems and artificial intelligence. What am I up to now? The journey is just beginning, and I'm excited to see where it leads!
