We are building a team whose area of focus will be web GUI development. This will be a horizontal team that will specialize in GUI development and will build GUIs for all our products. Our GUI development platform is a proprietary tool. It has an IDE (Integrated Development Environment) which comes with a rich library of widgets. It allows you to design the web page without having to go into details of the HTML/CSS, by using a drag and drop philosophy.
