What I'm looking for

I’m looking to own Oracle database operations in cloud environments, drive performance tuning with proactive observability, and deliver reliable 24x7 SLA support—while building runbooks/SOPs that keep teams effective.

I’m a Senior Oracle Database Administrator with 6+ years managing Oracle environments on-premises, in OCI, and on AWS RDS across 150+ multi-client deployments and 300+ database instances. I specialize in performance tuning, execution plan analysis, backup & recovery (RMAN), Oracle patching and upgrades, and configuration management across Oracle 19c SE2 BYOL environments.

I built and maintain a production database observability stack (Grafana, VictoriaMetrics, Grafana Alloy) that delivers real-time monitoring and proactive alerting—helping teams move from reactive-only incident response to faster, more predictable operations. In production, I deliver deep Linux-based Oracle support, schema management, and 24x7 SLA-driven troubleshooting.

At Software Mind, I administer 300+ Oracle 19c SE2 BYOL instances on AWS RDS, continuously stabilizing execution plans with AWR/ADDM-driven tuning (SQL Profiles, SQL Plan Baselines, and SQL Patches). I also executed a 1.2TB cross-schema Oracle Data Pump migration and coordinated backup & recovery validation, while developing runbooks and SOPs to support knowledge transfer and team onboarding.
