Marketing Action Platform

I have developed the UI for a Search Engine Marketing application platform used by companies such as IBM, Intel and others. I wrote the UI as a single page MVC application. It communicates with a Java back-end using JSON web services. This is a multi-user / multi-tenant application.
I have also developed a middle-ware to communicate the UI to the back-end in real-time using Node.js and Socket.IO, and a PDF generator using PhantomJS.


This is a DEMO application which lets users manage time-zones, helping you track the time of different cities.
I wrote it from scratch, as a part-time project, in 2 weeks time, using AngularJS, Bootstrap (as CSS framework) and a RESTful PHP back-end, based on Slim micro-framework.
