I'm currently building global endpoint and security-awareness programmes at Neurealm, where I architected a BlackBerry UEM environment for 2,000+ hybrid endpoints and reduced phish-prone behaviour from 18% to 2.4%.

I integrate device posture with Microsoft Entra ID, design SSL/TLS inspection controls, map threats through MITRE ATT&CK, and partner with infrastructure teams to sustain 99% compliance for critical server patches.

Previously at Kryptos Technologies (Crayon) and Capgemini supporting Alstom, I managed cloud and endpoint security controls, CSPM, SIEM/SOAR investigations, incident response, threat hunting, and phishing investigations using Microsoft Sentinel, QRadar, Splunk, and Cortex XSOAR.

Across more than 10 years in security and technical operations, I've supported identity administration, mobility platforms, network troubleshooting, escalations, and team operations. I focus on practical controls, clear reporting, and actionable remediation that strengthens organisational resilience.
