The order-processing system behind my site [1] is written in Common Lisp. It interfaces with Stripe for credit card processing and Easypost for generating mailing labels. The whole thing took me about two days to write and it has been working without a hitch for several years. It has more than paid for itself just in the time it has saved me in preparing international shipping labels manually.
I also have a prototype of a server-mediated version of the SC4 secure communications system [2] [3] written in CL. The code for this is a bit of a mess so it's not publicly released but if you're interested drop me a line. Contact info is in my HN profile.
