About

Full-stack developer based in Toronto, creating clean, thoughtful web experiences with a focus on usability and real-world impact.

With a background in software development across Korea’s hospitals, research centers, and public institutions, I’ve built adaptable solutions in complex environments. Now tutoring students in Canada, I share what I’ve learned while constantly sharpening my own skills. My approach blends clean code, user-first thinking, and clear design — always aiming to make tech feel a little more human.
