Key skills and experience
As a results-driven IT professional, I specialize in transforming complex, fragmented environments into secure, high-performance infrastructures. My expertise spans the end-to-end management of M365 ecosystems, advanced network orchestration, and robust firewall security. I have a proven track record of leading critical recovery and modernization projects—most notably redesigning a corporate network from the ground up to implement Role-Based Access Control and NAC-secured OT integration under high-pressure conditions. Currently, as Team Lead for IT Operations, I combine technical depth with strategic leadership to drive cloud consolidation, security monitoring and operational excellence.
Network
Standardization and security using HPE Aruba products like ClearPass (NAC). I specialize in migrating heterogeneous setups into unified, RBAC-secured infrastructures that bridge the gap between IT and OT.
Firewall
Advanced perimeter security and policy management via FortiGate. I focus on rigorous "Security by Design," replacing legacy configurations with modern, high-performance rule sets and secure site-to-site connectivity.
Microsoft
Full-stack administration of MS Entra and Intune. Expert in automated deployment via PowerShell (PSADT), identity governance through SSO/SCIM, and maximizing security scores within the Microsoft ecosystem.
Project Management
Strategic oversight of IT operations, including MS Sentinel (SOC) integration, VMWare optimization, and PRTG monitoring. I lead complex transitions, such as tenant consolidations and infrastructure modernizations.
