Architecture

Using AWS Amplify, this project has the following configured backend resources:

• 2 DynamoDB tables
  1. Save user attributes from external IDP provider (For future development)
  2. Save user survey responses to provide best recommendation onto their feeds
• A GraphQL API that allows the app to query data from the above 3 tables
• An S3 Bucket for storing the GeoJSON data used in the heatmap
• A Lambda Function for searching for similarities between FSAs
