With the real-time tool Playbook, you get complete control over your contact center. Through user-friendly "cards" that you place on the screen, you see all work in real-time. You can encourage and challenge your employees as well as discover and solve problems immediately when they arise. It simplifies and streamlines your work. All statistics are presented in real-time and can be displayed on a large screen, on a laptop, or on a mobile phone, while the coach is out on the floor and guides the salespeople to success. Worked on the development of this project in a team of three developers, sharing responsibilities for everything including development, testing, and deployment of the application. Used Node.js and Express.js on the server-side for handling efficiently various asynchronous input/output bound requests to services or databases without blocking the current thread. Technologies used in the project: Node.js, Express.js, WebSockets, MongoDB, Knockout.js (for the UI), Require.js (for dependencies), Q promise framework, Chai (for testing).
Victoria is an application that shows ratings of select call center agents on a competition wallboard. The conditions of these competitions are highly configurable.
Overview: The project is built on ASP.NET MVC and Web API, the front end was created with Knockout.js and JQuery, the data storage is a MongoDB database. SignalR is leveraged for instant updates from server to client. The project has a layered structure and the dependencies for upper layers are injected by using the IOC Castle Windsor library.
My Role: General development, both on server and client (browser) by using agile methodology.
