Create Flask application used by my customers to manage/store private information

I want to create a Flask app with the following feature : - Requires authentication (No need to implement it, but just add the skeleton for that part and maybe use a default login/password to start) - Roles assigned to users (the super user will first create users for customer, then each customer will be able to create users to share its own answers, documents) - Allow users to connect - Allow users to create/delete/list registers (a register is a group of questionnaires) - Allow users to create/delete/list questionnaires - Questionnaires are built from templates using a specific format see later in the description - Display questionnaires that the customer, or the users he created (with a specific role), will answer - Display some questions only when some previous questions have been answered (dependency between questions) - Store results - Show a list of those questionnaires - Allow users with write role to update those answers - Allow users with read role to view those answers - Allow users to fill next questionnaires only when previous have been totally answered (the required questions) - Export feature to CSV - Allow user with specific roles to create and list contractors managed by the user - allow users with specific roles to add/list/delete Tasks - create a docker image to run the thing (low priority but could help during development) The goal is to build a Python Flask app using a DynamoDB database (Please use DynamoDB local for now [login to view URL]) No need to implement the handling of users, I'll do it later using AWS Cognito user pool. I want the app to be built based on [login to view URL] As you can see it uses configuration file for the questionnaires [login to view URL] and this is exactly what I want, to be able to have someone else write the questionnaires. Use Yaml instead of Json, this should help us.
