**Web based Campaign Management Platform for small businesses**
We are developing a web-based campaign management platform for small businesses. The platform will allow businesses to communicate with their subscribers over different channels, including Email, Social Networking Sites, SMS, and others.
The backend for the platform is coded by us, and we are looking for talented and experienced developers to code the web front-end. The backend is coded with Ruby on rails and the front-end will be based on ExtJS 3.x. We have started initial development for the web front-end (and are willing to start it from scratch).
The specifications will be provided as wire-frames, and the JSON/AJAX API to the backend will be accompanied by examples. The developer will have live access to the backend for continuous integration.
As we don't have fine-grain specifications just yet, we will be willing to work in predefined bulks, or agree on price per page/use-case/other.
The basic requirements from the developer are as follows:
1. Proven experience in complex web applications.
2. Proven experience in ExtJS/Sencha.
3. Basic styling capabilities is a great benefit.
4. Being fluent in English is a must.
5. Russian speaking is an advantage
