I'm putting together a new resume, and one of my projects at a previous position involved a localization piece converting our app from English to Chinese (complete with redesign). I was wondering what the best way to indicate this project on a resume? It was my first time as a PM on one of these so I just want to make sure that I get the terminology right.
You probably did two things: Internationalisation and localisation.
Internationalisation is the process of changing an app so that it can be reasonably easy translated into other languages. For example, that involves making buttons not a fixed size, not hard coding string in your app which makes translation impossible, and so on.
Localisation is the process of adding a second, third, fourth language to an app.
