Have you been the main or sole backend specialist in your team?

If you were the main or sole Backend specialist in a team, it means you were responsible for developing, maintaining, and architecting the server-side of the application. In such a role, you usually have to make decisions about technology choices, design APIs, ensure security and scalability, and also interact with frontend developers and other team members.

It is important to be able to organize the workflow, plan tasks, and quickly solve emerging problems, as the responsibility lies with one person.
