Roman Sedaikin is a senior software engineer with 8 years of experience building cross-platform graphics and UI systems, specializing in Kotlin, Java, C++, C#, OpenGL and modern desktop UI tooling like Jetpack Compose. He contributed to JetBrains' high-profile Compose Multiplatform and Skiko projects, improving desktop image viewers, adding zoom/drag features, and stabilizing OpenGL rendering across macOS and other OSes. Previously he led core engine and windowing work at SpaceVIL and developed highly optimized OpenGL visualization and seismic-data processing tools in research roles, producing registered software and libraries for industry use. Roman excels at bridging low-level rendering, platform interop (Swing/AWT) and high-level UI APIs, and he architects automatic rendering-selection logic to match hardware and software environments. He pairs deep technical craftsmanship with a history of producing production-ready tooling and examples that help other developers adopt complex graphics stacks.
