I’m a cybersecurity engineer with 4+ years of experience securing cloud-native and hybrid enterprise environments, with a focus on threat detection and response. I build high-fidelity detections using Microsoft Sentinel SIEM, Microsoft Defender XDR, and CrowdStrike Falcon, then drive investigations through KQL-based engineering and XDR timelines.

I implement identity-aware Zero Trust access controls and automate detection and response workflows via SOAR. I also integrate security telemetry across cloud environments (AWS), grounded in threat intelligence and MITRE ATT&CK-based detection engineering, including phishing investigation and triage.

In my recent role, I managed WAF rule lifecycle using Cloudflare Terraform for IaC-driven change management, configured Cloudflare web application protection, and provided real-time WAF telemetry and threat signals to the SOC. I configured Zscaler ZIA/ZPA for 3,000+ users to enable secure access to cloud-based CAD/PLM applications and tuned Sentinel analytics rules to reduce false positives.

I’ve also managed Fortinet Security Fabric for manufacturing and engineering clients with 45+ FortiGate devices, supported incident investigation and RCA across web/application layers, and strengthened security posture with SOC collaboration. Across endpoints, I’ve operated CrowdStrike Falcon EDR on 5,000+ endpoints and created custom IOC detection rules and automated containment playbooks to accelerate response.
