What I'm looking for

I seek a hands-on Android engineering role where I can improve app performance, mentor teams, work with Kotlin/MVVM/Clean Architecture, and deliver scalable, production-quality mobile products.

I am an Android developer with 8 years of experience building scalable, production-grade mobile applications for consumer and enterprise use, with a strong focus on performance, stability, and code quality.

I specialize in Kotlin and Java and apply MVVM and Clean Architecture, OOP and SOLID principles to reduce technical debt, improve load times, and lower crash rates—delivering measurable improvements such as reduced response times and increased user retention.

I collaborate closely with product, backend, and design teams, lead code reviews and refactoring efforts, and have successfully delivered multiple Play Store releases and region-specific apps adopted by hundreds of users.
