Error on CMS and database query optimization via AWS, Node.js, and Linux EC2 instances

We are running a mobile quiz game on AWS. It has a couple of bugs that need to be ironed out. Specifically there's a CMS that is meant to load quiz data onto the app but it isn't populating on the app client itself. Secondly there is a very long login time that requires a fresh login every time the app is opened. This error is centralized around a couple of postgres queries.

These services are running on AWS linux EC2 instances, Postgres, and Node.js

We are unsure of how to optimize to solve these problems so we are posting on here to hopefully find someone who can solve it for us.

技能: Amazon Web Services, node.js, Linux, MySQL, PostgreSQL
