Nix, Common Lisp, Emacs and literate programming.
My passion project is cl-nix-lite, a Common Lisp package scope for Nix, without Quicklisp.
I also maintain tomono, a multi-to-monorepository merge tool. Itβs written entirely as a Literate Program.
My work is dual licensed under AGPLv3 and commercial licensing. Contact me for details (payment options include a donation to the FSF)
