I manage secure, highly available enterprise Windows infrastructure and vulnerability remediation.

India
Message

At ClaySys Technologies, I administer enterprise Windows Server environments across production and development systems, managing Active Directory, DNS, DHCP, Group Policy, IIS, Windows Services, and user administration.

I've helped remediate more than 100,000 security vulnerabilities using Tenable Security Center while maintaining system availability and minimizing downtime. My work also includes Windows patching, scheduled maintenance, vulnerability assessments, backup verification, disaster recovery validation, and root cause analysis.

I troubleshoot Windows Server, SQL Server, SharePoint, IIS, scheduled tasks, and production applications, while providing L2/L3 escalation support and technical documentation.

Earlier desktop support roles strengthened my hands-on experience with Windows 10/11, Microsoft Office, VPN clients, system imaging, software deployment, hardware repair, LAN networks, Wi-Fi routers, printers, and SLA-driven incident resolution.
