Close-up Translations is a WordPress website I did for Alexandra Salmon-Lefranc, a talented English and German to French translator. WordPress is turned into a simple CMS but had to support three different languages plus the opportunity to add more in the future.

The language part of the project is powered by QTranslate which allows an easy switch between each language and deals with all the backend parts. The rest of the site uses a classic page/category system.
