About

I'm Dmitri, a full-stack Software Engineer with over 11 years of experience. My foundation is Java and Kotlin, with deep expertise in Android — from architecture and SDK internals to shipping production apps used by real people every day. Beyond mobile, I build backend services with Spring and Ktor, work with TypeScript and Angular on the frontend, and am comfortable across the whole stack when the problem calls for it.
