India

Message

At Teleperformance, I monitored Chronicle SIEM and EDR alerts, analyzed 200+ daily events, and supported incident response. I tuned correlation rules to cut false positives by 15% and used Python and PowerShell automation to reduce manual analyst workload by 20%.

I authored MITRE ATT&CK-mapped incident reports and contributed production SIGMA detection rules. At Allcargo Logistics, I implement and validate firewall and VPN controls and diagnose ACL and routing issues; earlier, I supported security monitoring and vulnerability assessments at AAA Technologies Ltd.
