About

Hello! I'm Jung Ki Lee, an incoming Master's student in Electrical and Computer Engineering (M.S. ECE) at the University of Illinois at Urbana-Champaign, starting in August 2026. I previously worked as a Tech Manager at Superplanet, where I managed 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!
