Redmond, Washington, United States
Summary
🤩
RockstarDustin Campbell is a seasoned designer and software engineer with 15 years of experience building developer tools and language infrastructure from Redmond, Washington. He contributes deeply to the .NET ecosystem—working on Roslyn, Razor, the C# extension for VS Code, the WinForms Designer, and as a member of the C# language design team—bridging compiler internals and editor experiences. Dustin’s work spans compiler services, language server protocol components, SDK tooling, and build system automation, with notable contributions to the widely used dotnet/roslyn and vscode-csharp projects. He focuses on improving maintainability and performance, extracting and refactoring core logic, and smoothing SDK-style builds across platforms. Equally comfortable writing analyzers to catch subtle build and code issues as he is updating code generation and tooling, he operates where language design meets real-world IDE workflows. Beyond code, his pattern of small, impactful refactors and build-system improvements reflects a pragmatic emphasis on developer productivity and long-term code health.
