PROFESSIONAL EXPERIENCE

August 2004 to Present, Teachers-Teachers.com, Colorado/Maryland

Information Technologies Architect

 

Teachers-Teacherís is the largest internet based education recruitment service company in the nation.  With around a half million teachers, and over two thousand school districts, it maintains high profile and high usage websites that require an emphasis on dependability, availability and reliability.  Initially, was contracted to maintain and extend the web technologies. 

 

Company growth coupled with inadequate server architecture and maintenance caused a rapid shift in responsibilities to primary network and system administration.  Worked with the CEO and other stakeholders to achieve consensus and buy-in for a project to move to a more robust architecture.  Worked with stakeholders to vision, design, implement, and support the new server farm build-out.

 

The new architecture consists of domain integrated Windows 2003 servers, a holistic approach to security - firewall (stateful and proxied), network, server, operating system, application, data, Storage Area Network devices, Linux firewalls and Linux mail servers.  Customer-facing product uptime has improved by a factor of ten, and critical server, device, service, security, and network failures has been reduced to nearly zero. 

 

Designed and implemented a comprehensive monitoring solution for the server farm at several tiers (external interfaces, network, power, server/devices physical and logical states, services, and internal interfaces).  Monitoring probes include network health, VLAN segment health, network segment health, power, temperature, network controller, raid controller health, physical disk health, disk pool health, logical drive space, memory utilization, CPU utilization, services, internal and external interfaces.  Also implemented a tracking system with escalation functionality to allow administrators to easily identify and troubleshoot the nature and priority of a probe failure.

 

Designed and implemented a secure access plan to allow managers, developers, system administrators, and end users access to network and server resources via VPN, with firewall policies active directory group policies, and IPSEC control points.

 

Improved and re-launched a disaster recovery system that spanned facilities, network, servers, applications, and data (backup, retention, and recovery). The recovery system included both intraday, high-availability backups (SAN snapshots) and restore/forks (clones) as well as off-site media (tape), and testing procedures to ensure viable, verified restore/recovery points.

 

Technologies included Microsoft Windows, Microsoft SQL Server, Microsoft Sharepoint Services (2.0 and 3.0), IPSwitch iMail, Active Directory, EMC SAN, Watchguard Firewalls, Dell Switches, Symantec Backup Exec (v10), Microsoft Windows Update Services, IIS, Cold Fusion, DotNet (v1.0, 2.0, 3.0), Active Directory, Microsoft DNS, Linux Bind, SNMP, LDAP, IIS, Whats-up Gold monitoring, Wildfire Jabber IM, RhinoSoft FTP, and Sawmill Web Tracking.

 

October 2000 to Present, Contract, Colorado

Independent Systems & Network Administrator Consultant

 

Multiple engagements working with Corporate Internets, Intranets, and Web Hosting solutions in mixed environments.  Technologies included Unix (Solaris, BSD, Linux) as well as Windows (NT 2000, and 2003).  Solutions include complete server farm build-out, server consolidation through virtualization tools, maintenance, and expansion using Sun, Dell, and HP servers, Cisco routers, switches, and firewalls, as well as other third party Linux and Unix hardware.

 

Responsible for design and deployment of Anti-Virus software throughout corporate environments (servers, workstations, laptops).  Designed and deployed maintenance methodology for system patches and virus updates. 

 

Established and maintained standards & practices for initial server farm deployment, day to day operations, database replication, standby servers, Active Directory Maintenance, virus monitoring, and deployment of hardware and software clustering technologies.

 

Marquee projects to date:

 

Compass Marketing (Intranet/internet Server Farm)

Contracted to assess the continued use of their current network and server solution.  Worked with client to identify and pinpoint security, availability and reliability issues.  Based on recommendations, client built out a new server farm solution.  Was involved in the visioning, design, and implementation of their new solution.  A key component of the solution was combining several older physical servers running disparate software (in this case, Exchange Servers and Blackberry Servers) into one new physical server using VMware.  Technologies included Windows Server, Microsoft Exchange Server, Microsoft Sharepoint Portal Server, Microsoft Update Services, VMware (v1.0), Symantec Backup Exec (v9) and Clarion SAN.

 

X2Delta Networks (Web Hosting Server Farm)

Visioned, designed, and built (hands-on) a high-reliability/availability server farm and administered that farm for more than three years.  Environment is a mixed Windows and Linux environment, with Windows running ads, web, ftp, mail, and database services; and Linux running firewall and domain name services.  Designed and implemented security and maintenance protocols, including software upgrades, virus protection, and backup.  Technologies included Windows Server, Windows SQL Server, Windows Exchange Server, mySQL, Bind, ipchains, iptables, VPN, Cold Fusion, and Perl.

 

Sprint Mobile (Internal Development Server Farm)

Contracted to manage the build out and deployment of Sprintís mobile (4GL) development center in Denver.  Duties included coordination with multiple vendors and corporate departments throughout the country to arrange for network connectivity and hardening (security and virus protection). 

 

Newmont Mining Corporation (Intranet/internet Server Farm)

Initially contracted as a developer.  Duties expanded to making critical path decisions on existing and future deployments for mission critical intranet applications (Apache, Cold Fusion, Oracle).  Enhanced performance and security by implementing best practice processes in their existing environment.

 

Catholic Store, Inc (Intranet/internet Server Farm)

Contracted to perform as the SA for a small business with an eCommerce website and custom-built internal POS system.  Encountered a flawed Windows 2000/SQL Server installation which required a redeployment of the entire server environment to industry standards and best practices, including the construction of a fully-functional, integrated and secure domain/ADS environment, thus significantly reducing security risks and maintenance costs.  Positioned and provisioned a Cisco PIX firewall to ensure intranet and internet security.  Maintained network environment including keeping operating system, applications, and virus software patched and updated. 

 


Sanford Homes (Intranet)

Sanford Homes is national homebuilder, and has its headquarters in Denver.  Contracted to help Sanford employees leverage data via an intranet website from their AS400.  Responsibilities expanded to include security and operational oversight of the server farm and involved interfacing with all of Sanfordís operations including sales, construction, and warranty support.  Wrote Cold Fusion applications to leverage the LDAP functionality of Windows 2000 ADS for security.  Technologies included Windows 2000, Active Directory, Cold Fusion (4.0, 4.5, and 5.0), Microsoft SQL Server, stored procedures, dhtml, JavaScript, and DB2.
