Hi guys, We need a Javascript expert who can build javascript fields from our WPF portal and document how to build and use in websites. Experience in Backbone.js is a must. The right candidate will be able to read and understand the traffic arising on the WPF portal. DO NOT APPLY IF YOU DON'T KNOW Backbone.js. Backbone test will be performed for a long term position. Look forward to connecting you soon.
