@denislavrov
Android developer specializing in Kotlin, Jetpack Compose, and app stability.
What I'm looking for
I am an Android developer with 7+ years delivering high-quality mobile solutions for enterprises, startups, fintech and government clients using Kotlin, Jetpack Compose, and modern Android architectures such as MVVM, MVI, and Clean Architecture.
I have a proven track record of reducing crash and ANR rates to top-industry benchmarks, accelerating time-to-market, and improving app performance — for example reducing ANR to 0.2% and crash rate to 0.3% at a recent employer and cutting non-fatal errors by ~30% through process standardization.
I work well in international, cross-functional teams and independently, taking ownership of architecture and delivery, leading small teams, and shipping production features with low bug rates and measurable performance and reliability improvements.
