Oracle Database Administrator | Golden gate | High Availability, Performance & Automation

About

I am a Production-focused Oracle Database Administrator with 3+ years of hands-on experience managing mission-critical Oracle 11g and 19c databases in enterprise environments. I currently work as part of a self-managed DBA team, supporting business-critical applications with high availability, performance, and reliability as top priorities. I regularly own production databases end-to-end, including backup & recovery, performance tuning, HA/DR, automation, and incident management. I have independently handled P1/P2 production incidents, including database outages, performance degradation, and recovery scenarios, ensuring minimal downtime and quick service restoration. I have practical experience implementing and maintaining Oracle Data Guard, supporting RAC and ASM, and designing robust RMAN backup strategies aligned with enterprise RTO/RPO requirements. I strongly believe in automation-first DBA operations and have built shell scripts for health checks, monitoring, and alerting—significantly reducing manual effort and improving operational efficiency. While Oracle is my core expertise, I also have working exposure to PostgreSQL concepts, including architecture, backup basics, and replication concepts, which allows me to adapt quickly in multi-database environments. I enjoy working closely with application, middleware, and infrastructure teams, solving real production problems, and continuously improving database reliability and performance. I am particularly interested in product-based environments where databases are treated as critical platforms, not just support systems. Core strengths: Oracle Database Administration | Production Support | High Availability & DR | Performance Tuning | Automation | Incident Handling | Database Reliability
