Legit my only answer to fixing shit code for a nursing app at work is.....

Writing more shit code. Man the dude that developed this before had 0 clue what he was doing.....and because shit grew out of control there is shitcode everywhere.

I like writing shit code though. It is good practice.

Writing shit code without knowing is one thing. You really do reach expert level when you write shit code WHILE being fully aware of it.
