AE Backend Code Challenge

The goal of this challenge is to build a solution comprised of REST APIs that finds the closest port to a given ship and calculates the estimated arrival time based on velocity and geolocation (longitude and latitude) of given ship. Requirements are:

• Each user has a name and role. Each user can be assigned one or more ships. Develop basic REST APIs to manage users.
• Each port has a name and geolocation. Seed your solution with initial (or randomly generated) port data. No REST API is required for creating ports.
• Each ship has a name, a unique ship id, geolocation (current longitude and latitude of the ship) and velocity. Each ship can be assigned to one or more users. Develop basic REST APIs to manage ships.
• Develop an API which returns the details of closest port and estimated arrival time of given ship to the closest port.

Using C# is a must for this solution. xUnit is a must for testing. Aside from that, feel free to use any technologies/tools/frameworks/libraries ...etc you prefer.

Challenge delivery time should not be longer than a week.

1. As a consumer of the API, I want to be able to add users to the system.
2. As a consumer of the API, I want to be able to see all users in the system.
3. As a consumer of the API, I want to be able to update ships assigned to a user.
4. As a consumer of the API, I want to be able to add ships to the system.
5. As a consumer of the API, I want to be able to see all ships in the system.
6. As a consumer of the API, I want to be able to see ships assigned to a specific user.
7. As a consumer of the API, I want to be able to see ships unassigned in the system.
8. As a consumer of the API, I want to be able to update velocity of a ship.
9. As a consumer of the API, I want to be able to see the closest port to a ship with estimated arrival time to the port together with relevant details.

Feel free to make asumption on anything that is not stated in the description.
