A Mobile and Frontend Engineer who architects cross-platform applications and modern web experiences. My work centers on Kotlin Multiplatform, Compose Multiplatform, and the modern web stack — building systems that are maintainable, scalable, and actually ship.
Currently at TAJJI, I build internal libraries that power production apps across Android, iOS, and desktop. I've architected platform-agnostic SDKs, established complete DevOps pipelines, and led teams in shipping cross-platform applications that users rely on daily.
If you're building something interesting, let's talk.
