Summary
🤩
RockstarVasily Levchenko is a Senior Software Engineer based in Munich with over 20 years of systems programming experience and 11 years in senior roles across industry leaders like JetBrains, Yandex, Oracle, Intel and Sun. He specializes in low-level runtime and debugger engineering—most recently improving Kotlin/Native debug info and LLDB integrations for JetBrains and contributing tests and debugger fixes to the core Kotlin project. His background spans networking and device emulation for VirtualBox, JVM tooling and profiler design at Intel, and large-scale data and experiment infrastructure at Yandex, reflecting a rare blend of systems, tooling and backend expertise. Vasily is an active open-source contributor on high-profile projects (JetBrains/kotlin, kotlin-native), often focusing on hard-to-observe problems like object stringification, proxy type providers and debugger stepping through inlined code. Comfortable operating at the intersection of compilers, runtimes and developer UX, he has a track record of turning intricate low-level issues into practical, debuggable solutions. Colleagues value him for deep technical ownership and for making debuggers reveal useful, human-readable insight into complex language runtimes.
