For the coders/software engineers/whoever deals with code on a daily basis
I've been working as a software engineer for three years and my team and I have been working on this one app specifically. I was actually hired to work on this one app, so I basically saw it from the ground up. This codebase is huge, with thousands of lines and many external dependencies. Maybe it's just me but I know every single line. I can look at a log and tell you exactly where it's coming from. There are multiple developers on the app and they don't have the slightest idea of what is going on outside of what they coded. I know all of it.
Maybe I've hyperfixated on it or something but I love it. I'm also extremely good at refactoring code. Just looking at what it's currently doing and migrating it to do the same but using different things.
I have a great memory and impeccable attention to detail and they shine here.
I'd like to hear from other people in the same line of work!
