Hello! I’m Eun Kyoon.
I'm an Android developer with a rare combination: 3+ years of dedicated Android/Kotlin development paired with 12 years of systems and embedded engineering at Samsung Electronics. That background gives me a deeper understanding of the hardware and system constraints behind every mobile app — from Android-based device fleet management to embedded OS deployment — which I apply to building stable, performant Android applications.
Summary
Android developer (Kotlin, Jetpack Compose, MVVM, Coroutines/Flow) who shipped the award-winning berlinHistory app — 50K+ downloads, DigAMus Award winner (2020), Grimme Online Award nominee (2021). Backed by 12 years of systems and embedded engineering at Samsung Electronics, I bring a rare combination of app-layer craftsmanship and system-level understanding to every project.
