What I'm looking for

I'm looking to build and improve modern Android applications, apply clean architecture and modularization, solve complex performance issues, and collaborate with cross-functional teams while mentoring other developers.

I've built and maintained Android applications across retail, banking, streaming, and social platforms for more than 10 years. Most recently, I developed a major online retailer's Android application with 5+ million downloads, improving performance, functionality, and modularization from 42% to 53%.

At Energize Global Services, I led end-to-end development of a secure mobile banking application, including transaction history, balance inquiry, mobile payments, authentication, and account management. I also led developers, reviewed code and merge requests, improved build and release processes, and created technical documentation for architecture, security, and UI design.

I'm hands-on with Kotlin, Java, Android SDK, Jetpack Compose, Clean Architecture, MVVM, MVI, testing, and refactoring legacy monoliths into maintainable modular codebases. I've also taught Android development at Netology, creating and reviewing student assignments and supervising graduates.
