In this contract position for the New England Journal, I developed multimedia supplementary journal article content as single page web apps. My primary duty was converting old interactive web content for pre-2014 journal articles from Adobe Flash to HTML5. The conversions contain extensive JSON and Javascript work, and often include additional features to the Flash versions such as responsive design. Frameworks worked with included JQuery, vue.js, D3.js, apexcharts, and Datamaps. I also assisted with new interactive content as needed.
