I'm working at this company where I have to update their app both for Android and iOS and it was originally coded by what seems to be one guy, that has written some of the worse code I've seen (I've seen pretty bad code when I was at uni), there is so much uncommented code, commented code with no real reason on why it's commented, variables that are one or two letters, Lots and Lots of magical numbers for things like images! And for the first few weeks working on the iOS app I was also still learning objective-c and had to look at his code for reference, I cringed so much.

I take pride in my commented code, I take pride in writing description for methods and having my variables at the top of a class and explain exactly why it's a constant. I'm also only just a recent graduate.

This guy that worked out this app is a senior developer, now working on security software for a bank, how is he even allowed to code?
