4. Experience in writing Unit tests with pytest.
5. You have worked with Docker, docker-compose.
6. Familiarity with the AWS ECS stack.

We want you to care about

1. Good object oriented design
2. Performant APIs
3. Analysing why queries are slow and how to go about improving them.
4. Understanding DNS, Load balancing, Caching and Hashing.
5. Customer data and privacy.
