Wikimedia CH is looking for a HTML/Node.js/JavaScript/CSS contractor to help with Kiwix, the offline Wikipedia reader 

The Kiwix project (http://code.kiwix.org/http://www.kiwix.org) is an offline reader for web content. Contents are stored into a local ZIM file that can be browsed later on.

Although Kiwix' main use is that of an offline Wikipedia reader, it also supports other kinds of content (other Wikimedia projects, Stackoverflow, TED talks, etc.)

The ZIM archive we currently generate from Wikimedia dumps is not very mobile-friendly. We need someone to modify the scrapper (https://github.com/kiwix/mwoffliner in Node.js) so as subsequently to improve/preprocess the html/css/js content.A list of task can be found here:
https://github.com/kiwix/mwoffliner
https://github.com/kiwix/kiwix/labels/be-mobile

This is a free (as in free speech) project, so a bit of experience with interacting with a community would be a plus. But any one can join.

If you're interested, please send an email to 
Emmanuel Engelhart <emmanuel.engelhart@wikimedia.ch> and 
Matthieu Gautier <mgautier@kymeria.fr>
