Define multi-phase architecture with support for load-balanced firewalls, web servers, database, etc. Implement phase 1: web servers load balanced via DNS, installed and configure switch with public and private VLANs, replaced database server with faster hardware. NHC Communications Inc. Consultant / Sr. Solaris UNIX Administrator September 2002 to December 2002, February 2003 to March 2003 Customized and documented Solaris 8 installation on SUN Fire 280R and 220Rs. Disks were mirrored with Solstice Disk Suite, and the OS was hardened and secured according to Telco security requirements. Topcom, TMS, and Oracle 9i were also installed and documented. A complete Installation Manual and Operations Guide were delivered for each server. Support was also provided to the Development and QA teams. Air Canada Consultant / Sr. Solaris UNIX Administrator April 2001 to April 2002 A one year contract to install, configure, maintain and document a BroadVision 5.5 installation on a 4 tier architecture, consisting of load balanced iPlanet web servers, four BroadVision application servers, four BookSmart servers, and a clustered Oracle database server, all running on SUN hardware. Responsible for defining standard server configurations, including Solaris OS, disk allocation, 3rd party applications, users/groups, directory structure, etc. Responsible for approval and documentation of all changes to UNIX servers. Write scripts and procedures to transfer files, start/stop and maintain applications (synchronize data, etc.). Review UNIX security, firewall rules, and network design. Recommend changes to improve security against DoS attacks, application security bugs, hackers, etc. Participate in architecture and application volume tests. Lead fail-over tests of network, server, and application components. NuRun / Quebecor Consultant / Sr. Solaris UNIX Administrator December 2000 to March 2001 Install a SUN Enterprise 450 with SUN DiskSuite, InterShop, and Sybase.

    • Application servers (using ArrowPoint CS-800), monitoring and client access servers (ssh and sftp). Access to Internet services would be controlled by firewall rules, whereas internal security would be handled by ACLs on the CS-800. Back-end databases and transaction software would be hosted on two Sun Clusters. Sadly, Normal Solutions closed before this solution could be implemented. Teleglobe Inc. / Up2 Technologies Sr. Solaris UNIX Administrator December 1998 to January 2000 Lead installation and participate in design of Highly Available network (firewalls, routers, switches, etc.).
