Bad Apples

Inherited a legacy codebase and rebuilt the back end to handle production-level scale.

-Exercised data-driven decision making using a custom script to test database query speeds of MongoDB and PostgreSQL.
-Generated 10 million dummy records and seeded them into PostgreSQL to simulate production level data.
-Deployed with Docker to ensure consistent application behaviour between local and deployed services and to easily horizontally scale service.
