Client-side JS work in ongoing project

JS developer needed for great product development. We have a forms design technology that is widely used, that we are re-implementing using client-side JS using Knockout and other JS. We now have an early prototype and we are looking to extend the team with experienced JS developers, ideally with experience of Knockout. You will be able to work either short term on specific parts, or on an ongoing basis, and be able to operate in an agile iterative way with our small teams in UK and New York. In the first instance we'd be interested to understand your skills, experience etc. and look forward to your questions, thought and conversation, but not so much your boilerplate.
