Hi, I'm rosu
An Android engineer with 6 years of experience building live streaming and real-time AV features. I enjoy working with Kotlin Multiplatform and exploring how mobile tech can scale across platforms. Right now I’m at Tencent Music Entertainment, but I’m also looking for overseas roles where I can build cool stuff and keep a balanced life.
