Summary
🤩
RockstarMatthew Yacavone is a software engineer with nine years of experience specializing in the intersection of computer science and mathematics, particularly functional programming, dependent type theory, and formal verification. He has hands-on compiler experience, including a contributed GHC patch that extended Haskell's type system and a public presentation at ICFP’s Haskell Implementors’ Workshop. His open-source contributions span foundational work in Cubical Agda—implementing higher-inductive type support and core mathematical structures—and cryptographic testing and bindings for the Cryptol project, demonstrating both theoretical depth and practical engineering. Academic research in knot theory produced a co-authored paper and a computational tool for manipulating Legendrian knots, reflecting an ability to turn abstract math into usable software. Based in New Jersey, he blends formal methods research with real-world compiler and testing work, often operating in community-driven, peer-reviewed development processes.
