I have come to like asking questions to people running companies that use CL, and I have Arnold in my radar for quite some time. He contributed a while back to my cl-str library, and at that time, I don’t recall how many Lisp projects he had in his Github, but not as much as today. Since then, he created ScreenShotBot (an open-source screenshot testing service) and he released a few very useful Lisp (and Elisp) libraries.
