Professional summary

I am an experienced IT infrastructure professional with more than 20 years of hands-on experience in systems administration, enterprise support, and hybrid cloud environments.

I currently manage and optimize large-scale Windows, VMware, and AWS infrastructure supporting global corporate and maritime operations. My work includes automated provisioning, server lifecycle management, incident handling, vulnerability remediation, and operational support.

I have extensive experience with Microsoft 365, Azure AD Connect, Exchange Online, Active Directory, Windows Server, DNS, DHCP, Group Policy, and multi-domain hybrid identity environments. I have also supported migrations from on-premises Exchange to Microsoft 365.

Throughout my career, I have delivered first- and second-level support, resolved complex escalations, and provided guidance and training to support teams. I am comfortable working in 24/7 operational environments and supporting executive users and distributed business units.

I have contributed to office deployments, infrastructure projects, network and telephony implementations, virtualization administration, security tooling rollouts, and cloud-based platform operations. I bring strong troubleshooting skills, a service-oriented mindset, and a commitment to reliable, secure IT operations.

I am always ready to take on new technical challenges and contribute my infrastructure administration experience to teams operating complex hybrid environments.
