Yes. In fact, I do almost all of my coding in Common Lisp. I'm even getting paid for some of it :-) I'm working part time for Intel helping them maintain an internal design tool written in CL. I run my own email server that runs a spam filter that I wrote in CL, and the e-commerce system that processes orders for my crypto dongle is written in CL. As an exercise I wrote a sudoku solver in CL a while back.

sorry to ask, but what about that cryptographic project? why didn't you pick CL?
Because that product was an embedded system running on a very small SoC. It only had 1MB of flash and 192k of SRAM. It's theoretically possible to run CL on a system that small -- Coral Common Lisp ran on a Mac Plus with 1MB of RAM back in the 1980s -- but nothing off-the-shelf will do that today.
(I did, however, put a little Scheme interpreter on it as an easter egg :-)
I do have some CL code that supports the crypto project. The back-end for this:
https://stage.sc4.us/sc4/sc4tk.html
is written in CL (though all the actual encryption is done client-side in Javascript). I also have some prototype crypto code that I don't really use for anything, including this double-ratchet implementation:

and some elliptic curve code:
