What types of tasks have you implemented or solved using MongoDB?

MongoDB is often used for tasks that require flexible data storage with a dynamic structure. For example:

• Storing user profiles with different sets of attributes.
• Logging events and user actions, where records may have different fields.
• Caching data with quick access and scalability options.
• Implementing product catalogs with variable characteristics.

In Python projects, I used MongoDB for storing web application data, where the document structure could change without schema migrations, which sped up development and made maintenance easier.
