Graduate Security Engineer using Microsoft Sentinel and KQL to raise detection coverage from 0% to 100% in controlled tests.

For my MSc dissertation at Sheffield Hallam University, I built a controlled Azure PaaS security lab using Microsoft Sentinel to test three MITRE ATT&CK-mapped scenarios. I used KQL and Azure telemetry to investigate detection gaps, then developed and validated scheduled analytics rules that raised scenario-level detection coverage from 0% to 100% in the controlled tests.

At Edo State Internal Revenue Service, I supported the network and user environment for an Azure-hosted government platform. I monitored Sophos Firewall activity and system logs, configured firewall rules and VPN connectivity, and helped maintain 99.9% platform availability.
