In today’s episode, we bring Leandro Ostera, a seasoned software engineer, who’s currently leading the OCaml build system team, with the mission of making OCaml SaaS ready!

Join us as this episode is packed with a variety of topics, where we mainly focus on the OCaml ecosystem, compare it to other languages and frameworks, but also dabble into very obscure topics such as Idris (hint: it’s a programming language), and explore concepts such as routine blocking, scheduling, types, and other issues.
