The goal of this task is to build a backend service with a SQL database that implements a predefined REST API.
In particular, the candidate is expected to:

• Ensure that the service does not slow down as the database grows;
• Ensure that no data can be overwritten due to a race condition;
• Demonstrate their approach to unit testing;
• Organize code in a readable and maintainable way.
The candidate gets access to a private GitHub repository with the task description, a project boilerplate, and API tests.
They submit their solution by creating a Pull Request.
The evaluation is based on the results of the automated functional tests and the code review scorecard that covers more advanced aspects within the target competence.
