Cordova App Developer Needed For Ongoing Work

General information for the app: It is a cordova app, using OnsenUI and we use the Intel XDK editor to do builds. App is on Android and IOS.
Kind of development: Customization of existing app
Num. of web pages/modules: 2
Description of requirements/features: We regularly need developers for Cordova hybrid apps. We have one here we want to add some features to. Please only bid if you can start right away and commit to at least 15 hours per week.

Initial Tasks:
- Finish implementing the Bit6 Cordova Plugin - We've imported code from the sample project already and it seems to work fine, but the HTML and CSS needs editing to fit with the app. The demo app for instance has instant messaging too, which we do not want - we just want voip calling and video calling.
- Add field to settings page for phone number (used as username for Bit6)
- When VOIP or video calling setting is enabled, trigger a pop-up when calling contact to select Phone, VOIP, or Video Call
- Calling functionality (using Bit6)
- Investigate landscape view not triggering on IOS
- Implement Facebook analytics plugin
Specific technologies required: JS, Angular, Cordova
