Tell us about your experience with Oracle and your overall project experience.

In projects with Oracle, I worked with versions 11g and 12c, involved in configuring and optimizing database performance, writing complex SQL queries and PL/SQL procedures. My experience includes creating and maintaining backups, setting up replication, and monitoring database health using built-in tools. I also participated in data migration and index optimization to speed up queries.

For example, in one project, I optimized queries that were taking too long by analyzing execution plans and adding appropriate indexes, which reduced response times from several minutes to a few seconds.
