Top SchoolRolf Kvinge is a Principal Software Engineer based in Madrid with 19 years of experience building and stabilizing large-scale .NET and Mono ecosystems. Now at Microsoft, he has deep expertise across runtime, SDK, linker and tooling work—contributing to high-profile projects like the .NET runtime, Mono, and MAUI where he improves AOT, linking, and platform bindings. His contributions span backend systems, test automation and mobile/iOS samples, reflecting a pragmatic blend of low-level runtime fixes and higher-level cross-platform developer experience. Colleagues rely on him to diagnose tricky edge cases (PE/PDB handling, AOT compilation quirks, and build/test robustness) and to make incremental improvements that prevent regressions. Trained originally in physics, he brings a methodical, detail-oriented approach to complex tooling and platform problems.
