Peergrade

We recently switched from MongoDB and the Python library MongoEngine to PostgreSQL and Django in order to:

• Better leverage @{GraphQL}|tool:3820| (using the @{Graphene}|tool:4611| library)
• Allow us to use the autogenerated Django admin interface
• Allow better performance due to the way some of our pages present data
• Give us more a mature stack in the form of Django replacing MongoEngine, which we had some issues with in the past.

MongoDB was hosted on mlab, and we now host Postgres on Amazon RDS .
