- Threat Triage (Kill Chain): Triaged over 100 monthly P1 incidents across Linux, Windows, and web apps using Cyber Kill Chain mapping : achieving mean time to triage.
- Forensic Log Analysis: Conducted a deep-dive forensic analysis on CloudWatch Logs, VPC Flow Logs, CloudTrail, and Redshift audit logs to identify IOCs, anomalous access patterns, and the root cause of security events : documented findings with a full chain of custody for enterprise clients.
- Threat detection via scripting: Engineered Python and SQL anomaly detection model on 50M+ log rows to classify threat signatures and predict security incidents, reducing undetected incidents by 60% and cutting mean detection time by 45 minutes.
- Vulnerability Remediation: Identified and closed critical misconfigurations in IAM policies, S3 ACLs, and Redshift security groups; applied AES-256 encryption (KMS), and fine-grained RBAC — achieving 100% audit compliance across all reviewed accounts.
- Incident Playbook (Published): Sole author of the globally deployed AWS Knowledge Center SOP on cluster-level incident response — adopted by thousands of AWS customers; internally authored multiple playbooks covering containment, forensic workflows, and escalation criteria, reducing escalations by 35%.
- Disaster Recovery / Business Continuity: Automated multi-region snapshot replication and failover for Redshift: validated RTO.
