What I'm looking for

I’m looking for a role where I can lead threat intelligence and proactive threat hunting, improve detection and incident response workflows with automation, and support strong security posture through thorough analysis and clear executive-ready reporting.

I am a results-driven Cyber Security Analyst with a strong background in network engineering and firewall management. In my current role at American Airlines, I monitor and analyze security alerts, investigate Indicators of Compromise (IOCs) and Indicators of Attack (IOAs), and deliver daily and ad-hoc threat intelligence briefs to senior management.

I also build and optimize threat intelligence workflows using intelligence platforms like Rapid7 and Flashpoint, along with automation tools such as XSOAR. I am known for detail-oriented threat hunting, correlating and attributing malicious activity, and providing actionable findings during medium and large-scale security events—backed by incident handling commendations exceeding company SLAs.
