Rubén Badilla

@rubnbadilla

Senior Oracle DBA at Oracle, resolving RAC and Data Guard incidents while reducing average downtime by 30%.

At Oracle, I resolved high-severity RAC and Data Guard incidents, reducing average downtime by 30% and meeting 99.9%+ SLA targets. I handled complex service requests across on-premises, OCI, and hybrid environments.

I supported Exadata Cloud Service and Exadata Cloud@Customer deployments, cloud migrations, and high availability and disaster recovery configurations. I used AWR, ASH, and system metrics to investigate performance issues across compute, storage, and database layers.

Before Oracle, I was Database Manager at Megacable SA de CV, overseeing Oracle and MS SQL Server databases for billing and control systems. My earlier roles included Oracle Database Engineer at SOFTEK (Hewlett Packard & IDB Group), Database Manager at PAQUETEXPRESS, Oracle Database Specialist at Xerox, and Oracle DBA at INEGI.
