Steve currently architects core coding agents for GitHub Copilot and has a track record of improving developer experience via compiler, runtime, and tooling work that spans front-end navigation, CSS isolation, and back-end SignalR integration. His contributions to high-profile open-source projects (dotnet/aspnetcore, Blazor, Razor) show a rare combination of language/runtime design, pragmatic engineering, and attention to testability and diagnostics. Trained as a mathematician at Cambridge, he pairs rigorous analytical thinking with hands-on system-building and occasional experimental projects like WebWindow and Mobile Blazor Bindings.
