SeniorMartin Josefsson is a seasoned freelance developer with 12+ years building production software in functional languages (OCaml, Clojure, Elm, Rust) and pragmatic systems work in Javascript/TypeScript and C, with a strong focus on Bitcoin and blockchain applications. He has shipped crypto and smart-contract work for startups and enterprises, and has experience modernizing large web apps and backend systems (GraphQL/Relay, Node, Java, Elasticsearch).
