I'm currently supporting Oracle 19c RAC clusters and Active Data Guard disaster recovery for TechTrack Technology's NIC client in Riyadh, including patching, RMAN recovery, Data Pump, and Bash automation.

At Geidea Technology, I supported PostgreSQL, Oracle, MongoDB, and MS SQL across development through production environments. I configured Patroni, etcd, and Keepalived high-availability clusters, improved performance through query and index tuning, and managed PostgreSQL disaster recovery and backup tooling.

Across Motive, Ericsson, Nayatel, and ITZ-Solutions, I've administered Oracle, PostgreSQL, MySQL, MariaDB, Cassandra, MongoDB, and MS SQL. My work includes AWS RDS and Aurora provisioning, Terraform and Ansible automation, database migrations, clustering, replication, security, backup and recovery strategy, and performance tuning.
