• Server 2012 R2 to Server 2019 upgrade for school-based Hyper-V servers – Initial testing of an in-place upgrade failed, Microsoft could not provide a solution. Based on knowledge gained from Microsoft I created a successful partially automated procedure from portions of my server integration code. I will be collaborating with the SCCM team to automate the upgrade process for 2000+ servers.
• I am now managing 13,000 lines of PowerShell code for the server integration tasks. Circa July 2019 550 lines of code existed.
• The average execution time for the server integration process is now 50 minutes.
• I added support for Windows Server 2022 during November 2021.
• I developed code which proactively monitors over 3,400 physical and virtual servers.
• Embedded within the monitoring framework is code which enables the servers to automatically resolve faults in Hyper-V replication, DHCP, and some unresponsive operating system states.
• Via PowerShell I generate reports which enable management to proactively allocate larger blocks of IPv4 addresses to schools. I developed code which modifies the respective DHCP scopes.
• I implemented and deployed code which creates a centralized nightly backup of the DHCP configuration from each school.
• I created and executed code which extracted DHCP data from schools systems for capacity planning.
• I recently completed a major update of the server integration script to accommodate a new networking architecture while maintaining full compatibility with the current environment. I added support for VLSM, new DHCP scopes, and settings such as DNS addresses were moved from code to text files.
• I created multiple scripts to change the DNS IP address settings in the Hyper-V servers, virtual machines, and DHCP services.
• I receive requests from the SCCM team to create code to enable their processes to execute.

• I optimized existing PowerShell scripts for the configuration and integration of two Windows Server 2012 R2 Hyper-V Hosts with five virtual machines, three - 2012 R2 VM's and two - Red Hat Linux 6.4 VM's.
• I reduced the integration's deployment time by approximately 50%.
• I significantly reduced the quantity of manual input for the integration. For example I used plink.exe to automate tasks which were manually executed within the vi editor. I also used winscp.exe to automate copying files.
• I utilized Excel to create an integration checklist.
• I created a quality assurance procedure to verify the configuration of the integration.
• I created new versions of the integration scripts for Windows Server 2012R2, Windows Server 2016, Windows Server 2019, RHEL 7.7, RHEL 8.2, and CentOS 7.
• I created Red Hat and CentOS Kickstart images which enable automated custom settings per site. Previously the inherited RHEL 6.4 script block required the operator to manually enter the IP settings and the host name.
• Within the integration script I provided the operator with the ability to selectively execute blocks of code thus enabling the operator to both recover from errors and rebuild individual VM's.
• I created documentation for the pre-integration tasks and the integration tasks. I update the documentation as needed and I share it with the related teams.
• I also execute live demonstrations for my colleague, a NYC DOE employee, so he becomes aware of the process changes.
• I created a PowerShell script which locates and resolves Hyper-V replication problems.
• All blocks of code that execute changes are tested within an IT lab prior to being used within the production environment. Creating an IT lab was my first significant request to the Server Operations team.
• Daily tasks include receiving help desk (Cherwell) tickets, executing the scope of work, and updating the tickets accordingly.
