Tell us about your experience with databases and which systems you have managed.

I have experience working with relational databases such as MySQL and PostgreSQL, as well as with NoSQL systems like MongoDB. In projects, I have been involved in designing data schemas, writing complex SQL queries, optimizing indexes, and ensuring backups.

Additionally, I managed databases within DevOps processes: automating deployment and migrations using tools like Liquibase or Flyway, setting up monitoring and backups, and ensuring scalability and fault tolerance of databases in production.
