PROFESSIONAL EXPERIENCE:

Site IT Administrator (Windows System Engineer)

Confidential

Responsibilities:

  • Support new user provisioning in MFA environment.
  • Maintain Active Directory OU and sub-OUs for the site (Users, Groups, Computers/Servers.)
  • Upgrade (remediate) user workstations (mostly laptops) to use bitlocker and MFA, and perform rolling reimage to Windows 10.
  • Support user problems resolution, printing issues, file access approval tracking and management, transition users to recently-implemented ticket system and corporate help desk.
  • Bring all servers to current maintenance / patching levels.
  • Instruct and guide local IT support in implementing Windows file security best practices in an ITAR and OPSEC environment involving complex access and security issues.
  • Create, document, and implement a script (PowerShell) to re-establish all file security settings over a critical set of highly-sensitive engineering resources and documents- establishing at the same time a two-level role-resource security model in Active Directory (also partially scripted.) This script is designed to be re-executed at any time in order to ensure that data security precisely matches the policies encoded in a machine-readable (.,csv) document.
  • Migrate virtual machine servers from older end-of-life Hyper-V hosts to upgraded newer ones to improve energy efficiency, reliability, manageability, storage and memory utilization - shutting down 11 out of 15 physical hosts. Transitions performed variously by live migration; replication and failover; and VM cloning from WS2008R2 to WS2012R2 hosts. Some VMs required extensive reconfiguration of VHD architecture due to prior methods of resolving storage constraints: one is larger than 6.5 TB.
  • Migrate six virtual machine servers over the wire and mostly live from New York State site to Redmond site via Hyper-V replication and planned failover. Some were larger than 2 TB.
  • Implement Business Continuity / Disaster Recovery support by upgrading a surplused but under-warranty physical host, creating Hyper-V replicas of all critical virtual servers, and then relocating the host to Eastern Washington.
  • Construct and implement automation to ensure that BC/DR replication remains healthy with very minimal if any manual intervention.
  • Construct automated scripts to report on security and BC/DR health for audit purposes.
  • Work with permanent site IT manager (FTE) to plan for implementation of better virtual computing environment involving blade server hosts in either Hyper-V or VMWare clusters with shared storage.
  • Document recommendations for future development to corporate IT management in CT and NC.
  • Propose and implement small datacenter environmental monitoring and alerting solution using ABC NetBotz appliance and temperature-humidity sensors with email and SMS alerting capabilities.
