What I Do

Areas of Expertise

From cloud governance to day-to-day IT support — here's where I bring the most value.

🔐

Security Policy & Governance

Design and implement security policies covering access control, endpoint standards, approved software, and Azure RBAC to strengthen compliance posture.

☁️

Cloud Administration

Manage Azure and AWS environments including subscription oversight, cost optimisation, resource rightsizing, and development environment hygiene.

🖥️

Systems & Infrastructure

Deploy and maintain Windows Server environments, Active Directory, network configuration (VPN, NAT, load balancing), and enterprise applications.

👥

End-User Support

Deliver responsive onsite and remote IT support, manage onboarding/offboarding workflows, and ensure smooth day-to-day operations for teams.

🛡️

Access Control (RBAC)

Enforce least-privilege principles across Azure resources, code repositories, SharePoint, Confluence, and Jira to reduce attack surface and meet compliance requirements.

📊

Monitoring & Incident Response

Monitor security posture, escalate incidents, and drive continuous improvement through structured ticketing workflows and root-cause analysis.
