About Minsoo Kim (kmshack)
Minsoo Kim is an Android engineer known online as kmshack. For sixteen years, he has worked where mobile interface craft and implementation meet: motion, startup paths, responsive UI, performance, and accessibility.
His professional product work includes KakaoTalk, KakaoPay, KakaoMusic, and BugsMusic. Independently, he designs, builds, publishes, and supports apps such as BusanBus and ONEWallet. The technical blog documents Android engineering and product lessons from that work.
Some posts date back to earlier generations of Android. Read older articles with their publication dates, versions, and legacy notices in mind; they are an archive, not a promise that every API remains current.
