When he was a kid, Arthur wanted to be a stuntman or sewage worker. Time passed by and after graduating from ENS and obtaining a PhD, Arthur is now a research and development engineer at OCamlPro, where in specializes in Rust but sometimes still indulges in monad transformers. He is interested in performance optimization, software design, and crafting powerful and user-friendly tools. Despite never becoming a stuntman, Arthur enjoys deep dives in technical topics, and when not coding, he tries to learn how to play the trumpet and takes part in loudness contests with his upstairs neighbors' two years old child.
