I’m a Senior IT Operations specialist blending M365/Azure ops with OpsInt security intelligence.
MaltaWhat I'm looking for
I’m a Senior IT Operations & Service Delivery Specialist with 15+ years supporting global infrastructure in regulated banking/fintech, iGaming, and corporate environments. I combine hands-on M365/Azure/Entra ID administration with ITIL-driven incident/problem management and end-to-end service ownership.
I bring OpsInt (OSINT-based Operations Intelligence) to improve anomaly, fraud, and threat detection. I’ve consistently acted as a “one-person IT department,” owning service continuity through monitoring/alerting, patch management, endpoint security, and operational documentation.
I’m also the founder of ON-OFF®, where I bridge IT, security, UX, and human–AI interaction. Through freelance work, I build multi-domain operational models (“Layer Zero support flows”) that connect human factors with IT and security processes using pattern recognition and operational resilience research.
