Automated Survey with Java and Spark

This Spark application uses the Twilio API to create an automated survey conducted over SMS or phone call. The application reads a JSON object with questions into a Java object using Google's Gson library. It then interacts with Twilio and uses a factory-based approach to build TwiML responses, which are used to guide the user through the survey. The application stores the caller's response in MongoDB and displays the survey results on a dynamic dashboard. The code is well-structured and follows good object-oriented design principles.
