What I'm looking for

I am seeking senior mobile engineering roles where I can lead architecture and teams, build secure, scalable Android apps using Kotlin and Jetpack, and collaborate with product and customers to deliver high-quality production solutions.

I am a Principal Software Engineer with nine years of experience building production mobile applications using Kotlin and Java, focused on high-quality, well-documented code and robust architecture.

I have led and mentored engineering teams, designed complex system architecture, and delivered large-scale apps — including a mobile app with ~400,000 users kept under a 2% crash rate, PCI-DSS–certified financial apps, and an SDK used by 100+ clients. I have implemented MVVM and Clean Architecture practices and worked across Kotlin, Jetpack Compose, Coroutines, Retrofit, Firebase, and AWS to create secure, scalable solutions.

I prioritize code quality, operational stability, and close collaboration with product and customers to translate requirements into reliable mobile experiences.
