Ever had to work with a Web backend, which is written in C++, has 30000 lines of code and is contains php, JQUERY, HTML as well as a desktop UI? I have to do that right now. Now, I am not the most experienced dev with Web stuff but this is fucking ridiculous.

@jespersh your comment has to be a separate rant, ffs.

On topic, have you conaidered separating the project into several?

@psukys dude. I won't refractor that fucking piece of garbage code even with a gun to my head. It would probably be easier to just rewrite it with a designated web framework. There is so much code multiplication, bad Design in there. Also no comments and no tests. I will complete my task with that piece of shit and never touch it again if I don't have to.
