Expert IT Specialist Contractor via Broad Crossing Inc. | 7/2021 - 7/2023
New York City Department of Education, Brooklyn, NY
Contract
Accomplishments:
The contract job was renewed for two more years with a new job title via Broad Crossing Inc.
I managed 40,000 lines of PowerShell code for the server integration tasks. Circa July 2019 550 lines of code
existed.
As new requirements for the integration process arose I updated the code and the QA process accordingly.
I updated the code to function with Server 2022.
I 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.
Because I planned appropriately, when the entity changed its DNS settings, I only needed to update one text file
for the script and one tab for the QA process in the Excel worksheet template file.
I continued to increase the level of automation by reducing the amount of human input.
I added encryption. The process became more secure. The operator does not need to enter two pairs of
credentials.
I developed code that proactively monitors and manages over 3,300 physical and virtual servers.
The monitoring framework enabled the servers to automatically resolve faults for both Hyper-V replication and
DHCP and some unresponsive operating system states.
In addition, the framework ensured that Windows-based servers with more than 30 days of uptime are restarted
outside of normal operating hours. Before implementing the code it was not unusual to find servers that had not
been restarted for several years.
Additional details are at www.garrigan.info Page 2 of 6
I created multiple scripts to change the DNS IP address settings in the Hyper-V servers, virtual machines, and
DHCP services.
Via PowerShell, I generated reports which enabled management to proactively allocate larger blocks of IPv4
addresses to schools. I also created code that updates the configuration of the respective DHCP scope.
I implemented and deployed code that creates a centralized nightly backup of the DHCP configuration from each
school.
I received requests from the SCCM team to create code to enable their processes to execute.
On Fridays, I conducted online classes for interns and the server team.
Within related internal correspondence, my name appeared in the list of recipients along with members of
management.
Key technical and educational staff members reached out to me instead of their in-house bureaucratic IT groups
for assistance and timely decisions.
Specialist / Classroom Connectivity - Server QA Deployment Engineer Contractor - IIT | 7/2019 - 7/2021
New York City Department of Education, Brooklyn, NY
Contract
Accomplishments:
From the existing PowerShell scripts, originally 550 lines of code only for Server 2012R2, I developed a cohesive
process using PowerShell which manages the configuration of the Hyper-V Host servers and multiple Windows
and Linux virtual machines. Approximately 30,000 lines of code existed at the end of the first contract.
I created new versions of the integration scripts for Windows Server 2016, Windows Server 2019, RHEL 7.7,
RHEL 8.2, and CentOS 7.
I reduced the integration's deployment time from hours to approximately 50 - 60 minutes. The VM s are
simultaneously created and configured.
I created a quality assurance process to verify the configuration. I utilized Excel to create an integration checklist
with a QA tab
I significantly reduced the quantity of manual input for the integration. For the Linux VMs, I used plink.exe to
automate tasks that were manually executed via the vi editor. I also used winscp.exe to automate copying files to
the Linux VMs. For Server 2016 I leveraged PowerShell Direct and for Server 2012R2 I developed an
innovative solution.
I created Red Hat and CentOS Kickstart images which enable automated custom settings per site. The existing
RHEL 6.4 script required the operator to manually key in the configuration.
Within the integration script, I provided the operator with the ability to selectively execute blocks of code thus
enabling the operator to recover from externally caused errors and rebuild individual VMs.
I created a PowerShell script that locates and resolves Hyper-V replication problems.
All blocks of code that execute changes are tested within an IT lab before being used in the production
environment.
I create and update documentation for the pre-integration tasks and the integration tasks. I share it with the
related teams.
I also execute live demonstrations for my colleagues.
Daily tasks include receiving help desk tickets, executing the scope of work, and updating the tickets.
