Expert IT Specialist Contractor via Broad Crossing Inc.

New York City Department of Education

Contract

Brooklyn, NY

July 2021 - Present

• The contract job was renewed for two more years with a new job title via Broad Crossing Inc.
• I am now managing 15,000 lines of PowerShell code for the server integration tasks. Circa July 2019 550 lines of code existed.
• As new requirements for the integration process arise I update the code and the QA process accordingly.
• I updated the code to function with Server 2022.
• 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.
• Recently the entity changed its DNS settings. Because I planned appropriately 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 continue to increase the level of automation by reducing the amount of human input.
• I added encryption. The process is now more secure. The operator will not need to enter two pairs of credentials.
• I developed code which proactively monitors and manages over 3,300 physical and virtual servers.
• The monitoring framework enables the servers to automatically resolve faults for both Hyper-V replication and DHCP and some unresponsive operating system states.
• In addition the framework ensures that the Window-based servers with more than 30 days of uptime are restarted outside of normal operating hours. Prior to implementing the code it was not unusual to find servers which had not been restarted for several years.
• I created multiple scripts to change the DNS IP address settings in the Hyper-V servers, virtual machines, and DHCP services.
• Via PowerShell I generate reports which enable management to proactively allocate larger blocks of IPv4 addresses to schools. I have also created code which updates the configuration of the respective DHCP scope.
• I implemented and deployed code which creates a centralized nightly backup of the DHCP configuration from each school.
• I receive requests from the SCCM team to create code to enable their processes to execute.
• During Fridays I conduct online classes for interns and the server team.
• Within related internal correspondence my name appears in the list of recipients along with members of management.
• Key technical and educational staff members reach to me for assistance and timely decisions instead of their in-house bureaucratic IT groups.

July 2019 - July 2021

• 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 10,000 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 VM’s I used plink.exe to automate tasks which were manually executed via the vi editor. I also used winscp.exe to automate copying files to the Linux VM’s. 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 VM's.
• 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 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.
