App Overview

Signup/Login System with Firebase

• Firebase takes care of caching login credentials to prevent constant logging in
• Valid emails are required

Live Notifications

• Notifications can be sent out through the admin interface using the Firebase SDK and Firebase Cloud Messaging
• Notifications tell users when to expect kits to be dropped off and picked up for each county

Construction Tutorial

• Step by step tutorial is shown above
• There are also external Youtube videos for further construction assistance

Face Shield Submission

• Users must first complete final quality checklist
• Then they can submit the shields through a Google Form (temporary)
• They are then greeted with a congratulations screen

Backend Overview

Completely Serverless

• Uses AWS API Gateway/Lambda Functions written in Python 3.8
• Deploys to the cloud from a CloudFormation template
• I wrote a custom script for easily adding to the CloudFormation template

Uses an AWS Aurora (Postgres) Database

• Database schema is normalized in 4NF (no multi-valued functional dependencies)
• Uses a DB trigger to keep global constructor statistics about the number of shields built and broken
• Backend uses AWS Secrets Manager to securely connect to the DB

Admin Interface Overview

• UI is not complete, it is extremely basic right now
• Built in React with Material UI and functional components
• Deploys here using Github Pages (login credentials are required)
