At NielsenIQ, I triaged 500+ daily SIEM alerts and tuned detections, reducing MTTR by 20% and false positives by 15%. I managed CrowdStrike Falcon EDR across 1,000+ endpoints, including malware triage, containment, and post-incident reporting.

I mapped adversary TTPs with MITRE ATT&CK and investigated IOCs using OSINT and threat-intelligence lookups. I also strengthened AWS IAM and CloudTrail monitoring and supported PCI-DSS, SOX, and CIS audit readiness.

I built a Sentinel Detection Pack with five analytic rules, five KQL hunting queries, and a Python IOC triage tool. My other projects include a Splunk incident response simulation lab and a Python phishing email analyzer.
