About

I’m Artem, a Software Engineer with 12+ years of experience specialising in Android app development and backend services.
Passionate about Kotlin, Clean Architecture, and Reactive Programming, I’ve led teams to deliver award-winning apps and high-performance solutions.
In addition to Android development, I’m proficient in Python and Java, with hands-on experience in Linux environments, Docker, and containerised workflows. I’m also familiar with iOS development and backend systems, enabling me to contribute across the full stack.
