PROFILE
Christina Aravantinou
Contributed to the panther-analysis repository by developing and enhancing security monitoring features focused on cloud and AI/ML environments. Delivered two AWS Bedrock monitoring rules using Python and YAML, enabling detection of abnormal token usage and guardrail interventions to strengthen governance and observability. Improved notification clarity for GitHub branch policy overrides by including branch names in alert titles, leveraging the GitHub API and backend development skills. Addressed operational efficiency by disabling a noisy Auth0 brute-force detection query, reducing alert fatigue and resource consumption. Demonstrated a methodical approach to rule development, security analysis, and collaborative code review within a cloud security context.
