Summary
🤩
Rockstar🎓
Top SchoolBart De Smet is a partner-level software development engineer based in Redmond with 11+ years crafting language runtimes, compilers, and core frameworks at Microsoft. He has driven large-scale distributed event processing and edge computing platforms that power products like Cortana and Azure Intelligent Edge, blending deep CLR and .NET expertise with systems-level thinking. A longtime steward of Reactive Extensions (Rx) across .NET and JavaScript—contributing to flagship repos like dotnet/reactive and RxJS—he focuses on compiler and operator design that improves core expression evaluation and library maintainability. Bart’s strengths lie at the intersection of foundational CS theory and pragmatic engineering: type systems, virtual execution engines, and high-performance streaming engines. He also teaches and evangelizes advanced topics as a Pluralsight author and former Visual C# MVP, bringing rare depth in both implementation and developer education. Less obvious: he pairs low-level runtime work with practical constraints for tiny-edge deployments, optimizing for minimal memory and power while preserving expressiveness.
