Experience

Expert IT Specialist Contractor via Broad Crossing Inc.

New York City Department of Education

Contract

Brooklyn, NY

July 2021 - Present

  • 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.
