Summary
🤩
Rockstar🎓
Top SchoolGrégory Leocadie is a Senior Software Engineer with a decade of experience specializing in program analysis, language tooling and software re-engineering, currently building observability infrastructure at Datadog. His background includes designing static analyzers and porting large-scale codebases and engines (including a 4M-line x64 migration and porting a dataflow engine from Java to C#) from his time at CAST and Criteo. He has deep practical familiarity with a wide spectrum of languages—C/C++, Java, C#, OCaml, Lisp, Perl and domain-specific languages—and a particular affinity for functional programming and compiler-like program manipulation. Comfortable in both R&D and production settings, he has repeatedly delivered language front-ends, translators and analyzers used in industrial tooling. Based in France with research-oriented graduate training, he brings a rare blend of academic language theory and hands-on systems experience that surfaces in robust, long-lived engineering solutions.
