Hey, thank you for your inviitation. I have looked through your specs and your project seems to fit perfectly into my profile. I have been freelancing since 2007, starting with python + wxWidgets (later PySide/QT) desktop apps. In 2009/2010 I fell in love with Django and this is what I am doing 99% of the time today! ;)
Over the time, I got deep insights into djangos core and contrib apps and their changes over time. I have got experience with several 3rd party tools and utilities like django-socialauth, oauth2 (consumer and provider), django-rest-framework, django-tastypie, django-mptt (tree structures), django-haystack (indexed search with SOLR backend), django-grappelli, django-bootstrap3, django-angular and many more... Of course I am familiar with frontend libraries as well, such as jQuery, Bootstrap and Angular.js.
Apart from that, I know how important test driven development is and how to write unit tests ;)
Please do not hesitate to contact me if you have questions. Thanks!
Greetings from cold and cloudy Germany
