Lead internal security awareness initiatives, including employee security training programs and simulated phishing campaigns.
Coordinate with external security vendors to conduct periodic penetration testing and vulnerability assessments, including managing testing scope, scheduling, remediation tracking, and follow-up verification.

IT Support & Business Systems

Provide L1–L2 technical support for employees across the organization, troubleshooting issues related to Microsoft 365, ERP, networking, and SaaS platforms.
Manage user provisioning, permissions, device setup, and access controls across enterprise systems.

Hands-on experience administering Microsoft 365 environments, including identity and security management.
Experience managing Azure and AWS cloud infrastructure.
Strong knowledge of networking, VPNs, firewalls, and virtual networks.
