Reflex
Reflex is a website engine I build for my website with the intent of commercializing it. It is written in PHP with the intent of being modular, so you could add plugins to do pretty much anything.
While I never finished the project (because some things I wanted were too much demanding for PHP), this website still runs on an early prototype of Reflex.
I might restart the effort someday, and there’s a strong possibility that I will be switching to another programming language.
