Have you dealt with database management systems before?

Yes, I have experience working with database management systems (DBMS). Specifically, I have worked with relational DBMS such as MySQL and PostgreSQL, performing tasks related to data schema design, writing SQL queries, optimizing performance, and ensuring data integrity.

I am also familiar with NoSQL databases, such as MongoDB, where I used document-oriented data storage for flexible handling of unstructured data.

Within DevOps practices, I set up automated database backups, monitored system and performance status, and automated deployment and schema migrations using tools like Liquibase or Flyway.
