ContribKanban is a project I started in January of 2015 to provide Kanban boards for Drupal.org project issue queues. It started out as a MEAN - Mongo (Parse.com), Express, Angular, and Node application and then morphed into a progressively decoupled Drupal 8 application. The source code can be found on Github: https://github.com/mglaman/contribkanban.com
