What I'm looking for

I'm available immediately for fully remote work from Thane, India, with flexible time-zone overlap.

At Control-S Scanning Solutions, I managed Windows Server environments for multiple SMB clients and maintained 99.9% infrastructure uptime through monitoring, troubleshooting, and preventive maintenance.

I administered Active Directory, DNS, DHCP, and Group Policy, and managed Sophos firewall security, VPN, and access controls. I also handled backup and disaster recovery with Veeam Backup & Replication, including DR drills and RTO/RPO validation.

At GNP Group, I managed Windows infrastructure and IT operations across three business locations. I improved WSUS/SCCM patch management and compliance tracking, reducing patch-related system downtime by 25%.

Earlier, at AkzoNobel India Ltd, I led Windows XP to Windows 7 migration activities for 500+ enterprise users with zero data loss. I’ve also supported 24x7 remote operations for USA and Canada clients.
