At Accenture, I monitor and investigate security alerts using IBM QRadar, Microsoft Defender XDR, and Google SecOps/SOAR. I also develop and optimize SIEM correlation rules, KQL hunting queries, and SOAR playbooks to improve detection coverage and reduce false positives.

Previously, as a Senior Systems Engineer at Infosys, I performed 24×7 SOC monitoring and supported incident response through evidence collection, impact analysis, documentation, and escalation. My work has also included phishing analysis, threat hunting, vulnerability assessments, and security monitoring aligned with ISO 27001 practices.
