About

I’m a Tokyo-based Unity Engineer with more than five years of experience in mobile game development, covering in-game and out-game features, UI architecture, asynchronous systems, testing, and performance.

At Limit Break, I develop core gameplay and boss systems for Puzzle Panic. Previously at Rudel, I contributed to the development and live operation of three mobile games and later served as Lead Engineer.

My games include Planet Drop, available on Google Play and the App Store, and Pattern Hero, currently in development.

I use Chinese, Japanese, and English to communicate with team members in my day-to-day work.
