🤩
RockstarShea Levy is a Staff Software Engineer with 15 years of experience building resilient build systems, infrastructure, and back-end tooling, now at Anduril in Durham, NH.

Shea is fluent in Haskell and Nix-based workflows, having improved compiler and packaging tooling (cabal2nix, amazonka, haskell.nix) and streamlined reproducible builds for complex projects such as Plutus. He moves comfortably between low-level security and performance work (FreeRDP password handling, mmap fixes) and high-level architecture, having led AI engineering teams and shipping supply-chain optimization efforts. Colleagues rely on him for thorny build-dependency problems and for turning research-grade tooling into production-ready infrastructure.
