John Batista

I am an experienced Database Administrator with three years managing Oracle, MySQL, PostgreSQL, and SQL Server environments. I specialize in backup and recovery, database migrations, high-availability solutions, and performance optimization.

I have hands-on experience with RMAN, Data Pump, Rubrik, replication (DBLink), dbaascli, and tooling such as Oracle Enterprise Manager, Jenkins, CyberArk, and monitoring with Zabbix and Grafana. I work across cloud and on-premises infrastructures and participate in 24/7 on-call rotational support.

My approach is customer-focused: I manage incident response, ticket handling with Jira and Zendesk, and clear client communications while documenting maintenance procedures to improve resolution times. I also script and automate tasks to improve reliability and efficiency.

I hold academic credentials in Business and Analysis & Systems Development and support knowledge transfer through training and remediation of DBA learning materials. I seek to contribute strong analytical problem-solving and reliable database operations to a fast-paced technical team.
