I've previously worked on:
- TagLib#. I made it, porting from the C++ project and expanding it to support more formats.
- KIF. I redesigned the testing framework to run with an Xcode unit testing package and maintained it for a few years after.
- Stack Exchange iOS App. I developed the now-unavailable official app for this website.
- Stack Overflow public platform. You're experiencing some of my code right now. ;-)
