Have you had experience working with databases other than PostgreSQL?

Yes, in addition to PostgreSQL, I have worked with various databases such as:

• MySQL — a popular relational database management system, often used in web applications.
• SQLite — an embedded lightweight database, commonly used in mobile applications and for local storage.
• MongoDB — a document-oriented NoSQL database, suitable for storing unstructured data.
• Redis — an in-memory key-value store, used for caching and fast data processing.

Each of these databases has its own features and is used depending on the project requirements.
