This is an opensource job that will be hosted at github and submitted to the SailsJS community and hopefully posted at (  [obscured]  /markandrewj/sails-cassandra).

We're looking for a professional developer or team of developers to work on the redesign of some components of our Listing Program called Task Master. Task Master runs all the necessary processes to take an item ready to list, gather all the necessary information and push that information to the right channel.
