REST API Challenge

We would like you to implement a simple application which works with 3 REST APIs.

Suppose the user object only has three properties: id, name and role.

The first API allows the client to query a specific set of user objects by property where the request may look like this.

GET /users/?role=foo

The response should look like this.

[
  {
    "id": "977e3f5b-6a70-4862-9ff8-96af4477272a",
    "name": "java beans",
    "role": "foo"
  }
]

The second API allows the client to create a user object with a request like this.

POST /users/

{
  "name": "cookie bars",
  "role": "bar"
}

The third API allows the client to retrieve a user object given its ID

GET /users/977e3f5b-6a70-4862-9ff8-96af4477272a

{
  "name": "java beans",
  "role": "foo"
}

This is an open-end code challenge. We would love to see your approach to the problem.
The code maintainability is important.
Everything would run from Docker containers.
BONUS: Any log message must be non-blocking.
BONUS: Logs would be stored in a non-relational database.
BONUS: Usage of circuit-breakers.
BONUS: Usage of search engines
