I am a Senior Mobile App Engineer with extensive experience in mobile software architecture, design patterns, and development. For the past 4+ years, I have specialized in Kotlin for Android development, following Google’s recommended design patterns, clean architecture principles, dependency injection, Jetpack components, and Kotlin Coroutines for reactive programming. I am also proficient in Swift for iOS programming and am currently advancing my skills in Jetpack Compose and Swift UI.

I excel in translating designs into functional, clean, maintainable, extensible, and testable Android applications. My expertise ensures that the apps I build are not only high-performing but also user-friendly and reliable.
