Summary
👤
Senior🎓
Top SchoolKouji Matsui is a self-employed systems and runtime engineer with over two decades of hands-on experience building low-level software, embedded firmware, and .NET runtime tooling. He is the creator of IL2C, an open-source ahead-of-time translator that targets running ECMA-335 CIL/MSIL on everything from servers to tiny embedded systems, and maintains multiple F# metaprogramming and testing projects. Deeply versed in CLR internals (coreclr/corert/corefx), F#/C# language design and AST transforms, he bridges high-level functional design with native-level performance and footprint constraints. His background spans Windows kernel drivers, small OS development, hardware design, and cross-platform porting, giving him rare end-to-end perspective from silicon to managed runtimes. An organizer and educator in the Center CLR community, he pairs prolific OSS work with practical product and consultancy experience. Outside engineering he describes himself playfully as a “strawberry red slime mold,” hinting at a creative, curious approach to systems design.
