Education
Korea Advanced Institute of Science and Technology (KAIST)
2015 - 2022 | Bachelor of Science in Electrical Engineering (Minor: Physics)I started off with Physics but hit a brick wall with quantum mechanics, so I switched to Mechanical Engineering, only to find it was Physics 2.0. Eventually I moved to Electrical Engineering where I actually studied Computer Science topics like computer architecture, system security, blockchain, neural networks, web development, data structures, algorithms, and more.
Hankuk Academy of Foreign Studies (HAFS)
2011 - 2013 | Natural Science TrackMy high school years were a constant battleground with everyone vying for the highest scores, but I just couldn't get myself into prepping for college entrance exams. Instead I spent most of my time b-boying and studying weird stuff like particle physics. That eventually sparked my passion for science and engineering and led me to apply for a physics major later on.
