C1: I was the person with attention to detail. One guy built the system and led things. I spotted cracks in it, and patched it to be stable, then proposed a better system when they needed one.

C2: I was the "living documentation" for the entire system. There was plenty of docs, gigabytes of it in fact. Too much for most developers to know by heart. My job was to actually read it all and answer questions. I'd bring up things like how this portion is not optimized according to this specification here, or that portion is missing error handling N, which happens frequently, or this other server fallback is not being used. The system has millions of daily active users, so every time an API is called twice, that costs serious money. I'd also spot things like unstable hacks that were hidden in the code by some old programmers.

C3: Whole code was a mess. I spent half my time refactoring it, which also meant a few late nights sometimes, and chopping out thousands of lines of code a week. It cut down maintenance and bugs drastically. Where one thing would require 4 hours to do, it then required 10 minutes.
