Self Introduction

Career & interests overview

Android Engineer at LY Corporation (formerly LINE). I work on the LINE app used by ~100M users, focusing on platform updates, edge-to-edge support, and internal tooling.

As Tech Lead, I drive architectural decisions for the Android platform while mentoring team members. Kotlin and Jetpack Compose are my primary tools.

Beyond my day job, I build side projects with Ktor for backend and Nuxt 3 for frontend — especially in the motorsport tech space.

Outside of tech, I'm into cars — tuning, driving, and everything in between.
