Experience : 5+ Yrs

Built and provisioned Windows servers (physical and virtual) — OS installation, role configuration (AD DS, DNS, DHCP, IIS), and post-build validation.

• Deployed and managed VMware vSphere/ESXi environments across the enterprise —

administered ESXi hosts, managed vCenter Server, and handled virtualisation incident resolution.

• Provisioned and configured virtual machines — allocated CPU, memory, and storage resources;

performed VM migrations, cloning, and template creation for rapid server deployment.

• Managed VMware snapshots — created pre-change snapshots, monitored snapshot growth, and performed consolidation to maintain datastore health and performance.

• Configured and managed virtual networking in VMware — created port groups, distributed virtual switches (DVS), and VLAN assignments aligned to enterprise network segmentation standards.

• Performed VMware vMotion (live migration) and Storage vMotion to balance workloads across ESXi hosts with zero downtime during maintenance and capacity changes.

• Monitored ESXi host and VM performance using vCenter dashboards — tracked CPU, memory, disk I/O, and network metrics; identified and resolved resource contention issues.

• Managed resource pools and HA (High Availability) settings in vCenter to ensure workload

continuity and failover protection for critical virtual machines.

• Configured and maintained WSUS infrastructure for patch approval, deployment scheduling, and compliance reporting across server fleets.

• Executed server backup and restoration activities; supported disaster recovery failover validation and restoration testing for critical systems.

• Analysed Windows Event Logs (System, Security, Application) to identify root causes and prevent recurring infrastructure incidents.

• Managed disk configuration — volume extension, partition management, and storage optimization for enterprise Windows Server environments.

• Administered Active Directory (AD DS) including OU design, user lifecycle management, group memberships, delegation, and FSMO role management across multi-site domain environments.

• Designed and implemented Group Policy Objects (GPOs) for security hardening, software

deployment, user restrictions, logon scripts, and compliance enforcement enterprise-wide.

• Managed DNS zones, conditional forwarders, record management, and DHCP scope

configuration; troubleshot resolution failures and lease conflicts across the infrastructure.

• Monitored and troubleshot AD replication across sites using Repadmin and DCDiag, ensuring domain controller synchronisation and health.

• Resolved Kerberos, NTLM, and domain trust authentication issues in enterprise environments, minimising login failures and service disruptions.

• Administered SCCM/MCM for end-to-end patch management — configured Automatic

Deployment Rules (ADRs), Software Update Groups, and maintenance windows; tracked

compliance across server and workstation fleets.

• Deployed applications via SCCM using deployment types, detection methods, and device

collections; resolved deployment failures using CM Trace log analysis (ccmexec.log,

AppEnforce.log).

• Applied CIS security baselines, disabled unnecessary services, enforced compliance standards, and managed NTFS permissions across Windows Server 2016/2019/2022.

• Managed Hyper-V environments — VM provisioning, snapshot management, virtual switch, configuration, and performance troubleshooting.

• Automated Active Directory and server tasks using PowerShell — bulk user provisioning, group membership updates, password policy enforcement, and server health reporting.

• Managed end-to-end incident resolution and change requests via ServiceNow, maintaining SLA compliance and documenting root cause analyses (RCAs).
