At Premera Blue Cross, I processed indicators of compromise and integrated PowerShell and Python scripts into workflows for IOC ingestion and reporting. I also created threat intelligence briefs and presented cybersecurity topics to company-wide audiences.

At Seattle University, I helped build the security monitoring and response program, including SOC processes and Rapid7 monitoring rules. I handled reported security events, led responses to security incidents, and helped reduce response time from 1.5 days to 30 minutes.
