AngularJS to Python demo

I am looking for a proper working example of js to python communication. The purpose is for a mobile HTML5 app. I haven't found a suitable backend, node.js doesn't work here. I want a proper, working client-to-backend demo using AngularJS on the frontend, and Python on the backend. There doesn't seem to be good examples of this setup available online. There should be an example of passing sensitive data securely to the server, in addition to non-sensitive data. I also want the Python backend to write to a MongoDB and call a Luascript (for Redis) simultaneously. Perhaps gevent/greenlets would be useful here. The Python backend should be highly performant. Lastly, an example deploy on a cloud server, like Heroku, AWS, or Google App Engine.
