System infrastructure included HDS Lightening 9960, 3Par Inserv, NetApp F840c filers (clustered, using NFS and CIFS), Veritas NetBackup 4.5 (upgraded from 3.4) using Spectra Logic Gator 64k robotic library, load-balanced and replicated LDAP for Solaris authentication, BIND for DNS, load-balanced Apache, load-balanced and replicated MySQL, as well as remote access capabilities (MS RRAS for VPN and Lucent Max for dialup using MS IAS).

Managed the clustered Exchange environment and handled all improvements to Exchange ranging from migrating Exchange database to a larger volume to adding capabilities to Outlook Web. Managed and defined Active Directory users/user roles/security policy, implemented roaming profiles/folder redirection within the domain policy for specific departments. Designed/implemented's intranet website based on PHP and ported employee information into a centralized Oracle database.

Wrote several management scripts to automate tape duplication and rotation with Veritas NetBackup for off-site storage to improve disaster recovery plan. Implemented Qmail spooling server to identify spam and provide a localized buffer in case Exchange became unavailable. Wrote procedures to perform any administration task within Solaris, NetBackup, NetApp and SAN storage. Provided level 3 (end-of-line) support for the Operations department.
