Summary

Senior IT Infrastructure and Operations Engineer with 15+ years of enterprise IT experience and over 20 years of hands-on technical background. I specialize in designing, operating, and securing scalable on-premise, hybrid, and cloud infrastructures. My expertise includes virtualization (VMware, Hyper-V, Proxmox), Active Directory (on-prem & Azure AD), Microsoft Azure, infrastructure security, and Tier 1–3 IT operations. I have extensive experience supporting regulated, mission-critical environments with a strong focus on high availability and operational resilience. Recently, I designed and implemented an end-to-end RFID tracking system, integrating hardware, backend services, and databases to enable real-time asset and personnel visibility, auditing, and reporting in a warehouse environment. I work closely with security, development, and business teams to deliver practical, scalable solutions that balance technical depth with operational impact.
