Software Engineer at Nomadic Labs
France
Summary
🤩
Rockstar🎓
Top SchoolHugo Heuzard is a seasoned software engineer with 14 years of experience specializing in OCaml and systems-level tooling, currently building software at Nomadic Labs in France. He has a deep track record at firms like Jane Street and contributions to core OCaml projects—ocaml, dune, opam, js_of_ocaml and the widely used ocamlformat—demonstrating expertise in compilers, runtimes, build systems and developer tooling. His open-source work shows attention to correctness and maintainability: improving parsing, formatting, logging, and runtime primitives, and adding arbitrary-precision integer support and better error reporting. Comfortable across compiler internals and backend engineering, he blends rigorous math training with practical engineering from web frameworks to low-level language features. An understated strength is his history of improving developer experience (opam, ocamlformat, dune) so teams and tooling scale more reliably.
