Ordinary undergrad at Hanyang University (ERICA), majoring in Computer Engineering. Self-taught since 2016 — 10 years in and still hungry.
Builds robust backend systems in Java / Kotlin and crafts Android apps with Jetpack Compose. Chasing clean, maintainable code and systems that actually scale.
Back at Hanyang ERICA since the second semester of 2026 after finishing military service — classes by day, backend and side projects the rest of the time.
Away from the screen: 3D printing and modeling. Used to design, build, and maintain a printer from scratch; these days a Bambu Lab X2D handles the printing and Fusion 360 gets most of the attention.
