Simon Korzunov is a pragmatic software engineer with 10 years of experience building performant, cross-platform systems from low-level C++ and C# to modern Rust/WASM and functional F# UIs. He has worked across startups and large tech firms—including Microsoft, Dropbox, and Sourcegraph—shipping backend refactors, configuration improvements, and CI-hardened features as well as front-end reconciler and widget work on the open-source Fabulous MVU UI framework. Based in Virginia, he enjoys "mad science" engineering challenges that blend craft and empathy, often squeezing extra performance out of systems (he mentions a soft spot for Rust and WASM). His background in physics and long tenure in both game and cloud-focused teams gives him a strong foundation in systems thinking and pragmatic tooling. Colleagues rely on him to simplify complex architectures while keeping developer experience and testability front and center.
