Chrome Extension Additions

Greetings fellow freelancers! I need a JavaScript and extension expert to assist us in the deployment of a new application we have built. We have a few extensions deployed in the Chrome Web Store in 5 languages. We are approaching our applications completion date and we need you to help us modify our existing extension to offer the installation of our new app during the license and payment flow process. We use an auth server that handles licensing Oauth and Paypal checkout. It is written in Node.js running behind an Nginx reverse proxy. We use several node packages; Redis, MongoDB, Handlebars, Passport, and quite a few more. You'll have the opportunity to work with bleeding edge server JavaScript and most likely if you are good, offered more work in the future as we grow this business. Please put 'I can help' in the first part of your proposal so I know you understand this post and we'll take it from there.
