esy.sh, Reason, OCaml and Emacs. I maintain esy, the package manager, and it's ecosystem (native packages, compiler package and tools)
I constantly look marry open source with product development and user value. I primarily use Reason and OCaml. Currently interested in improving tooling productivity and reliability. Esy, in my opinion has the same primary goals as a tool, inspiring me to maintain it.
