Akira Technologies will share its experience of building a universal scalable high-performance platform for conducting surveys. Using MongoDB allowed replacing dozens unique survey systems with a single flexible solution, improved data and questionnaire reusability, simplified data analysis. We will also cover full-stack development and integration with Node.js, Hadoop, deployment to AWS Cloud, offline caching and stress-tecting the entire system with Tsung. A working prototype will be demonstrated including multiple surveys, dynamically rebuilding interface, geolocation, data analysis and visualization.
