Is your area of responsibility the integrations of the entire team or specifically your personal tasks?

As a senior developer, the scope of responsibility is usually broader than just personal tasks. It includes:

• Coordinating and integrating the work of the entire team to ensure consistency and code quality.
• Assisting colleagues, code reviews, mentoring.
• Participating in architectural decisions and planning.

Thus, the responsibility covers both one's own tasks and the integration and support of the entire team's work to ensure the project progresses effectively and without conflicts.
