What I'm looking for

I'm looking to lead threat detection, threat hunting, and incident response work where I can build detection content, automate security workflows, collaborate across technical teams, and strengthen enterprise cyber resilience.

At Fiserv, I lead enterprise threat detection, incident triage, and response across SIEM, SOAR, EDR/XDR, NDR, cloud, endpoint, email security, and DLP environments.

I hunt for sophisticated attacks using Google Chronicle, Microsoft Sentinel, IBM QRadar, MITRE ATT&CK, threat intelligence, and behavioral analytics. I investigate ransomware, phishing, malware, credential compromise, insider threats, and APTs through remediation and post-incident review.

Across Accenture, Infosys, and RailTel, I've engineered SIEM detections, correlation rules, cloud use cases, dashboards, and SOPs that improve coverage and reduce false positives.

I collaborate with engineering, cloud, infrastructure, DevOps, and IT teams to automate response workflows, strengthen controls, mentor analysts, and improve cyber resilience.
