Summary
🤩
RockstarDavid Müller is a pragmatic software engineer based in Germany with a decade of experience focused on backend development and test automation. He contributes to notable open-source .NET projects—improving cross-platform code coverage in coverlet and enhancing NuGet restore and MSBuild integration in the widely used Cake build system. His strengths lie in hardening build and test tooling, refactoring for reliability, and designing test suites that catch edge cases like async behavior and integer overflows. Colleagues rely on him for pragmatic solutions that improve developer workflows and reporting formats (e.g., Cobertura and source-link integration). He combines a deep attention to correctness with a bias for incremental, high-impact contributions across the .NET ecosystem.
