Rockstar🎓
Top SchoolRoman Zavarnitsyn is a Senior Software Engineer with 11 years of experience specializing in Android and full-stack development, currently leading platform work at Sentry in Vienna. He combines deep mobile expertise—contributing to prominent Android KTX libraries and custom UI components like ArcNavigationView—with backend and instrumentation work on Sentry and sentry-java to improve error and performance observability. His contributions to ktlint and other open-source projects show a strong focus on code quality, tooling and developer experience alongside pragmatic feature work. Roman’s background spans hands-on Android leadership roles and system architecture at companies like Runtastic and Bloom Diagnostics, reflecting both product-minded engineering and low-level platform instrumentation skills. A not-obvious strength is his frequent cross-cutting work: improving UX for error analysis while also implementing file I/O instrumentation and Kotlin language tooling.
