Message

At Oracle, I operate Exadata cloud infrastructure spanning hundreds of bare-metal servers. I improved patching success from 70% to 90% and helped increase customer-issue resolution success from 80% to 95%.

I also reduced Severity 1 recovery time from 90 to 60 minutes through root cause analysis and operational improvements. I use Terraform, Python, and Bash for releases and operational workflows, and applied generative AI to incident analysis, scripting, documentation, and automation.
