Summary

Rockstar🎓
Top SchoolRoman Volosatovs is a Principal Software Engineer with a decade of systems and runtime experience, currently based in Crans-Montana, Switzerland. He specializes in Rust, Go, Nix, Linux and WebAssembly, focusing on performance-critical low-level systems and runtime engineering. Roman has driven high-impact migrations and optimizations—most notably migrating wasmcloud to Rust and delivering a 14x performance improvement for NEAR’s WebAssembly runtime—while contributing as a maintainer to Wasmtime and other Bytecode Alliance projects. His open-source footprint spans infrastructure tooling (Home Manager, Cargo), embedded/wasm toolchains (TinyGo, Browsix) and distributed IoT systems (The Things Network), showing both breadth and depth across stacks. He blends hands-on kernel- and runtime-level work with product-minded delivery, having built transport-agnostic RPCs and multi-tenant Wasm runtimes used in cloud-native contexts. Outside engineering, an early background in jazz guitar hints at a creative, detail-oriented approach to problem solving.
