Could you tell about the positions and responsibilities of the participants in your last project team?

In my last project team, the following roles were present:

• Android Developer — responsible for developing and maintaining the mobile application, implementing new features, and fixing bugs.
• Backend Developer — created and maintained the server-side, API for interaction with the application.
• Tester (QA) — checked the quality of the application, wrote test cases, identified errors.
• Project Manager — coordinated the work of the team, planned tasks and deadlines.
• Designer — created layouts and visual interface elements.

Each participant was responsible for their area but actively interacted with others to successfully implement the project.
