At Kenvue, I played a crucial role in upgrading VMware environments, advancing from vSphere 4.1 to 5.5 using VMware Update Manager 5.1. My duties included troubleshooting both physical and virtual hardware, such as VMware ESX/ESXi and vCloud Director, achieving an exceptional uptime of 99.99%.I employed efficient deployment techniques for virtual machines (VMs), including template preparation, cloning, and exporting VMs in OVF format. I configured VMotion for smooth VM migration, High Availability (HA) for improved cluster resilience, and Distributed Resource Scheduler (DRS) for effective load balancing. I also addressed complex issues within VMware Horizon View, resolving advanced challenges related to virtual desktop infrastructure.In managing Windows Server environments, I handled clustering and failover processes across multiple versions (2008R2, 2012, 2012R2, 2016), managing both unscheduled and scheduled outages to ensure system reliability.I was responsible for designing and supporting Active Directory environments, managing Group Policy Objects (GPOs), Active Directory Schema, Organizational Units (OUs), LDAP, Sites, and replication. I provided third-level engineering support for Active Directory Domain Services on Server 2012 R2, ensuring effective directory services.In the Microsoft Azure cloud environment, I supported Infrastructure as a Service (IaaS) by creating and managing virtual machines via PowerShell scripts and Azure Portal. My responsibilities included managing Azure Storage Accounts and Affinity Groups, and configuring Virtual Networks and Endpoints for seamless operation.I also contributed to Continuous Integration (CI) and Continuous Deployment (CD) by developing and managing Build and Release Definitions, streamlining deployment workflows. Additionally, I captured and managed virtual machine images, configured disk attachments, and adjusted VM settings within the Azure Portal to enhance performance and reliability.

At H&R Block, I managed a highly virtualized environment, where over 90% of the infrastructure relied on VMware and Windows Server systems. My role involved overseeing virtualization monitoring and performance planning to ensure seamless operations. I was instrumental in deploying and migrating ESXi hosts, building new ESXi hosts, and migrating all virtual machines from ESXi 4.1 to ESXi 5.1. I worked closely with the network team to design and configure the network structure for these hosts, ensuring proper setup of NICs, VLANs, and subnets.I managed NIC teaming at the ESXi server level for redundancy and high availability, installed and configured vCenter Server, and integrated ESXi hosts within a cluster using vMotion and High Availability (HA) features. I also designed and implemented VMware-based solutions, deploying new virtual machines (VMs) and templates for various projects.In addition to creating and configuring VMs, I performed Physical-to-Virtual (P2V) and Virtual-to-Virtual (V2V) migrations using VMware Converter, managed VM snapshots, applied patches and updates to ESXi hosts, and adjusted vCPU and memory settings as needed. I also managed desktop pools, including manual, automated, linked clone, full clone, and RDP pools, tailored to user requirements.My responsibilities extended to Windows Server and Active Directory administration, where I managed Windows Server 2008 environments, including Active Directory, DNS, and DHCP. I built and maintained both physical and virtual Windows servers, handled OS upgrades, patching, and migrations, and administered Group Policy.Overall, my work at H&R Block ensured the stability, efficiency, and scalability of the virtualized infrastructure, supporting the company's operational needs and contributing to high service availability and performance.

During my tenure at Huntington Bank, I played a crucial role in the administration and optimization of Windows Server environments and Active Directory services. Windows Server and Active Directory Administration:• Administered Windows Server 2008, including Active Directory setup, and built new physical and virtual servers as required by projects.• Installed and configured Windows Active Directory Services, setting up domains and configuring DHCP, DNS, and IIS servers. Performed optimization and performance tuning as needed. Group Policy and Security Management:• Enforced domain security through Group Policy Administration and Active Directory Management.• Created and managed user and email accounts, adjusted user rights and permissions, and configured mail clients. Managed user and group accounts and their access control. Server Upgrades and Migrations:• Conducted in-place upgrades from Windows Server 2003 to Windows Server 2008 for both physical and virtual machines.• Created Active Directory users and groups, delegated authority, and applied permissions across member servers. Virtual Machine and VMware Management:• Built and configured new VMs and templates, allocating them to appropriate resource pools.• Installed VMware Tools and performed P2V and V2V migrations using VMware Converter.• Participated in the installation and configuration of vCenter Server and managed vSphere licensing.• Updated and upgraded ESXi servers using vCenter Update Manager. Remote Access and Connectivity:• Facilitated Remote Access using Terminal Services and VPN access to enterprise resources.• Established connectivity between the head office and remote locations for users. Citrix Server Support:• Provided support for Citrix Server Infrastructure, including XenApp for application virtualization.
