What I'm looking for

I'm looking to strengthen security operations through threat hunting, incident investigation, detection engineering, SIEM improvement, and practical automation that reduces manual effort and improves resilience.

I've supported mission-critical IT and cybersecurity environments for New Era Technology, TDCX, AIA, Amway, WHO, Qatar Petroleum, Shell, and Malaysia's Prime Minister's Office. In my current Senior SOC Analyst role, I investigate security incidents, hunt threats across EDR and SIEM platforms, coach SOC analysts, and improve detection logic.

I've built PowerShell and VBScript automation that reduces investigation and operational effort, including suspicious sign-in validation workflows and AbuseIPDB enrichment. My background also spans QRadar ownership, vulnerability management, SCCM, Active Directory, Windows Server, endpoint management, and resilient Hyper-V infrastructure.
