Yoda Response: Certainly, Avi. One situation where I had to collaborate with a team to solve a complex problem was during the development of an Event Management System as part of a project-based learning (PBL) initiative.

Our system needed to handle multiple types of users, such as admins and sub-admins, who had different levels of permissions for managing events. The challenge was to ensure that the system could efficiently handle user roles and permissions while maintaining data integrity and performance.

To address this, we decided to use MongoDB due to its flexibility and scalability compared to traditional relational databases. My contributions to solving this problem included:

1. **Database Design**: I worked on designing the database schema to accommodate different user roles and their permissions. This involved creating collections for users, events, and permissions, and ensuring that relationships between them were efficiently managed.

2. **Role-Based Access Control (RBAC)**: I helped implement a role-based access control system that allowed admins to approve or delete events while providing sub-admins with limited permissions. This ensured that the right users had the appropriate access levels.

3. **Collaboration and Communication**: I facilitated regular team meetings to discuss progress and challenges. I encouraged open communication and brainstorming, which helped us identify potential issues early and come up with effective solutions.

4. **Testing and Validation**: I was involved in testing the system to ensure that it met all requirements and handled different user roles correctly. This included writing test cases and performing both unit and integration testing.

By working together and leveraging each team member's strengths, we successfully developed a robust Event Management System that met all our requirements. This experience highlighted the importance of collaboration, effective communication, and leveraging the right technologies to solve complex problems.
