About Me
I am a student from South Korea following my passion for computer science at the Columbia University. I love expressing my creativity through personal projects and products. I am always learning new ideas, tools, and technologies to expand my horizons and improve my skills.
Besides work, I enjoy photography to cherish moments of my life, graphics design to cultivate my artistic side, and video games to improve my teamwork skills. I also love being exposed to different cultures and languages. I am capable of Korean, English, Japanese, and Chinese due to my fascination and multicultural background.
