About

I’m a 4th-year Computer Engineering student at the University of Toronto, passionate about building user-focused, scalable software. My experience spans frontend development, cloud infrastructure, and human-computer interaction.

At Genesys, I’ve developed cloud recording features that improved reliability for thousands of users worldwide. As GUI Lead at aUToronto, I designed and implemented an award-winning HMI for autonomous vehicles, working closely with a cross-functional team to integrate 10+ ROS stacks.

My background in fine arts — graduating #1 in design from Seoul Arts High School — helps me approach engineering with a strong design sensibility, blending aesthetics with functionality.
