Describe your experience working with databases and projects where you used them.

In my practice, I have worked with relational databases such as MySQL and PostgreSQL, as well as with NoSQL solutions like MongoDB.

In projects, I used databases for storing and processing user data, logging, and also to ensure the stability and scalability of applications.

For example, in one project, I configured automatic database backups and monitored their status using DevOps tools such as Prometheus and Grafana. I also participated in query optimization and index tuning to improve performance.

Additionally, I integrated databases into CI/CD pipelines to ensure automatic deployment and schema migrations during application updates.
