What I'm looking for

I’m looking for a fast-paced mobile role where I can lead Android architecture, ship performance-focused apps, and solve complex bug issues—while collaborating across iOS/Unity and improving developer workflows.

I’m an enthusiastic developer with 5+ years of experience in mobile development, with strong expertise in Android development. I’m eager to explore, enhance, and challenge my skills to their fullest, delivering reliable releases even in fast-paced environments.

At Feiwin Corp., I lead the Android, iOS, and Unity team as a project solution engineer, driving outcomes across multiple projects. I’ve delivered measurable improvements like reducing RAM usage by 45%, expanding app variants (14 to 34), and increasing the number of users up to 150k in 3 months through Jetpack Compose and multi-skin/theme support.

I also build tooling that improves engineering efficiency and quality—such as APK hardening and distribution tools that lessen dev work by 80%. I bring a modern Android architecture approach (MVVM/MVI, Clean Architecture) and a practical debugging mindset using advanced reverse engineering and performance/streaming tooling.
