The Learningbox is digital learning environment for MBO-schools. I extended the functionality of the existing web-application. My work involved, among other things:

• HTML, Javascript, CSS with a ASP + MySQL back-end
• A Drag & Drop user interface in Javascript.
• Creating a comprehensive overview page for student grades, using complex MySQL queries. I used AJAX to display additional information in mouse-over popups. AJAX.
• An user-interface to find students by class, course, name, etc. I needed to take user permissions into account and used AJAX to retrieve results faster.
• Exporting information in various formats, such as XML and CSV

I worked part-time in june-october 2010; and again in february-april 2011.
