About

Professional summary

I am a motivated cybersecurity and network professional with hands-on experience in network engineering, service desk support, and security analysis. I have worked in fast-paced operational environments where I monitored subsea cables, managed fiber optic circuits, and supported critical network services.

I have strong experience in incident response, vulnerability management, and security monitoring using tools such as SIEM platforms, Azure Sentinel, Microsoft Defender, and Splunk. I am comfortable handling security alerts, investigating suspicious activity, and supporting compliance with standards such as ISO 27001 and GDPR.

My background also includes service desk and infrastructure support at Newcastle University, where I delivered 1st and 2nd line support, managed user access, supported Microsoft 365, and resolved technical issues across Windows and Linux environments. I have worked extensively with Active Directory, PowerShell, vSphere, ServiceNow, and NU Service.

In network operations, I have monitored and managed circuits, escalated and resolved faults, supported engineers with site access, and maintained service continuity across 24/7 shift-based environments. I am used to prioritizing tickets, documenting changes, and communicating clearly with customers and internal teams.

I also bring technical knowledge in cybersecurity controls, firewall configuration, endpoint protection, encryption, MFA, and network monitoring. I have supported vulnerability scanning, patching, system hardening, and phishing awareness efforts to reduce risk and improve resilience.

I hold a BSc in Cybersecurity and Networks and an MSc in Data Science from Northumbria University, along with several certifications including ISO/IEC 27001:2022, Azure AI Fundamentals, CCNA, and Security+. I am eager to contribute my analytical skills, technical knowledge, and problem-solving ability to a team focused on security and operational excellence.
