Software Engineer at Microsoft
Barcelona, Catalonia, Spain
Summary
🤩
RockstarLluis Sanchez is a seasoned software engineer with 23 years of experience, based in Barcelona and currently working on Visual Studio for Mac at Microsoft. He is a strong back-end developer with deep expertise in .NET/Mono internals, version-control systems, and cross-platform compatibility—demonstrated by significant contributions to projects like Mono, ngit (a C# port of JGit), GitSharp, and MSBuild. His work spans core runtime fixes, robust XML (de)serialization, complex merge algorithms, and tooling that improves .NET portability on non-Windows platforms. Lluis also contributes to developer-facing tooling and UI layers through XWT and Sharpen, helping translate Java semantics to idiomatic C# and smoothing cross-platform UI behavior. Colleagues value his steady focus on correctness and edge cases—memory, threading, and version parsing bugs are recurring examples of where he adds measurable reliability. He combines pragmatic engineering with open-source stewardship, quietly improving foundational components that many higher-level tools depend on.
