About Me
“Happiness is when your
code runs without errors.”

Hello! My name is Joshua Song (SungHyun is my Korean name).

Formerly a psychology major, I am currently a senior CS major at Carleton College.
I spent about two years proudly serving in the South Korean military and
another year and a half gaining experience as a software engineer at a logistics startup.

My main strength is to communicate and never back down from challenges.
I take pride in my way of communication and the relationships I build with others.
When challenges arise, I act proactively and think of a way to resolve them,
rather than passively waiting for help.
I love to code, and I want to make an impact to the people around me.
