• Investigate and respond to incidents in AWS (CloudTrail, GuardDuty, IAM, VPC, etc.).
• Conduct log analysis and investigation across Linux systems.
• Contribute to and maintain playbooks, runbooks, and response procedures. Produce clear incident documentation, timelines, and lessons-learned reports.
