I have quite a lot of code that I have used for commercial web projects over the years. Mainly in my marketing agency (which was powered by common lisp). Some of this code might be useful to the wider community.
First one here: https://github.com/vinn2010/cl-stackexchange
If it’s useful, give it a star (because my goal in life is to collect internet points that can be used to buy absolutely nothing).
You can add these projects to Ultralisp.org to make them installable via quicklisp client!
