At Global IT Vision, I commission and tune Darktrace, LogRhythm, and CrowdStrike detection platforms, then investigate escalated alerts as an L2 SOC analyst. I reconstruct attack scenarios, identify root causes, support containment, and deliver prioritised remediation reporting.

I designed and validated an end-to-end NIST SP 800-61-aligned SOC using 10 components, including Wazuh, Suricata, CrowdStrike Falcon, TheHive, Cortex, MISP, and Palo Alto NGFW. I also conduct threat hunting, advise on security posture, and build actionable detection content from threat analysis.
