At Etisalat, I design and manage Oracle RAC, Data Guard, GoldenGate, and RMAN strategies for critical telecom databases, including on-premises-to-Oracle Cloud migrations with zero data loss and high availability. I also support MySQL, SQL Server, and MongoDB environments while improving query performance through AWR, ASH, trace analysis, and SQL tuning.
At CNS Middle East, I build HA/DR architectures including SQL Server Always On clusters, MongoDB disaster recovery on Docker, and PostgreSQL HA clusters using Patroni, pgpool-II, pgBackRest, and pg_stat_statements. Across Yash Technologies and Cognizant, I've maintained 100+ Oracle databases, delivered Oracle EBS cloning, patching, upgrades, Data Guard, GoldenGate, and L2/L3 production support, while applying Terraform, Ansible, Jenkins, Azure, AWS, and OCI automation.
