I worked as a DBA for about 3 years, managing and optimizing PostgreSQL and MySQL databases. My responsibilities included:

• Setting up and monitoring database performance.
• Query and index optimization to speed up operations.
• Data backup and recovery.
• Ensuring security and access control.
• Data migration and database version upgrades.

In one project, I implemented automated monitoring using Prometheus and Grafana, which allowed for timely identification of bottlenecks and reduced downtime. I also participated in a migration project from Oracle to PostgreSQL, where I handled schema and data transfer with minimal downtime.
