About

I am a Senior Android Developer with over 10 years of experience designing and delivering scalable, high-performance mobile apps. I specialize in Kotlin, Jetpack Compose, Coroutines, MVVM, and Clean Architecture, with additional cross-platform work using Flutter and Kotlin Multiplatform. I’ve led mobile modules serving 1M+ users and driven significant improvements in stability and performance, including roughly 90% reduction in crash rates and about 60% enhancements in performance.

I thrive on end-to-end delivery, stakeholder collaboration, and mentoring developers to build reliable, user-centric mobile solutions. I’m comfortable with CI/CD, production deployments, and contributing to long-term architectural decisions, while continually exploring cross-platform opportunities to maximize reusability and impact.
