Summary
🤩
Rockstar🎓
Top SchoolDavid Wengier is a Principal Software Engineer based in Melbourne with over a decade of experience solving hard engineering problems across compilers, developer tools, cloud services and consumer-facing applications. At Microsoft he has driven improvements to Roslyn, Razor and the C# support in VS Code, focusing on robust language-server behavior and compiler-driven code fixes that make developer workflows more reliable. Equally comfortable in C#/.NET, TypeScript and PowerShell, he pairs deep technical knowledge (including how syntactic sugar maps to compilers) with pragmatic DevOps and API design to reduce friction for other engineers. His background spans mobile, VR, installers and cloud-native services, reflecting a habit of exploring new platforms and keeping a broad toolbelt. He’s contributed directly to high-profile open source components in the dotnet ecosystem, and quietly enjoys making tooling that nudges developers toward secure, performant, and well-formatted code. Outside work he brings the same curiosity to small passions—he mentions Lego—hinting at an engineer who values craftsmanship and playful experimentation.
