Senior Android Engineer | Kotlin Multiplatform Engineer | Mobile Architecture & Security

I’m a Senior Android Engineer with 6+ years of experience building scalable, production-grade mobile applications, with a strong focus on Android, Kotlin, Kotlin Multiplatform, Jetpack Compose, and mobile security.

Currently working at Beltone Holding, building financial technology solutions across multiple financial products and platforms.

I enjoy designing and building mobile applications that are maintainable, scalable, testable, and secure.

My experience spans from building modern Android applications to designing shared cross-platform architectures and addressing real-world mobile security challenges.
