TECHNICAL SKILLS SUMMARY
August 2004 to Present,
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

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 (
