What databases have you worked with?

Worked with:

• MySQL/MariaDB: The primary database in most of my projects. Experience includes schema design, query optimization (indexes, EXPLAIN), working with transactions, replication.
• PostgreSQL: Used in projects requiring more complex data types and advanced features (e.g., full-text search, GIS). Familiar with optimization and configuration.
• SQLite: Used for small projects, single-page applications, or as temporary data storage.
• Redis: Used as a cache to speed up application performance, as well as for task queues (working with message brokers).
• MongoDB: Had experience working with document-oriented data models in projects where schema flexibility was a priority.

Also familiar with concepts and principles of other DBMSs, but main practical experience is focused on the ones listed.
