Digitize

This project began as the SCU COEN 315 - Web Architecture and Protocols final project. Not surprisingly, it was abandoned the day after it was submitted for a grade. It has since turned into an exercise in converting a serverful web app into its serverless equivalent using AWS managed services.

This repository holds the backend of the site.
