Hi There, Angular JS will do good at front end to interact with APIs Mongo DB will be robust enough to handle the distributed survey data. AWS EC2 is my recommendation for Cloud environment NODEJS is my preference for wrting APIs, web services All code will be well commented and using version control system GITHUB (preferred). For load balancing, we can use memcache logger, it is depends upon the language as if we are using NODEJS so we can use winston I'm a pro MEAN stack developer from a small development team based in India, We'll be dedicated to this project and available in chinese timings as well.
