Hired to evaluate the state of IT as the company transitioned from a small to mid-size organization. I propose a phased approach to rebuilding IT from the ground up. Projects are presented in a manner that's absorbable to a non-technical audience. After agreeing to the necessity of given project, vendors are cross-shopped, budgets are proposed and solutions are selected. As the IT workload becomes more project based, I hire, train and mentor additional staff. Team building:o Hired and trained additional staff to provide Helpdesk services, Systems Administrationo Assigned Projects based on past expertise and interest o Selected trainings for employees Disaster Recovery & IT Architecture:o Proposed and began implementation of Storage Replication, Virtual Machine replication, P to V migrations, DAS to SAN storage migrationo Selected and evaluated offsite location for replicated backups and complete business continuity o Selected and evaluated hardware vendors for SANs, virtualization hosts, networking and backupo Compared feasibility and cost of private cloud technology v. colocationo Implemented Voice over IP telephony systemo Implemented Redundancy for the firewalls, isps, and network core. Security & Compliance:o Re-evaluated PCI compliance and Client IT audit requestso Proposed multi-phased plan to rebuild backups, implement disaster recovery, address Desktop security, close holes with public facing applications and provide fault tolerant network and server topologieso rearchitected backup procedures and technology to meet backup requirements: Implemented backup Exec 2015, VEAM, hardware based deduplication and offsite target replicationo Evaluated and began implementation of Desktop management, encryption and Desktop security controls

Member of a team responsible for building Dealer Dot Com’s corporate infrastructure. I was a project lead during the complete re-architecture of our LAN and WAN across three corporate offices and the migration from a homogenous linux based architecture to a heterogeneous Linux, Windows and OSX environment. Nearly all systems were migrated into a highly redundant VMware ESX cluster, leveraging SANS and blade centers. High availability being a key concern, applications were load balanced and databases were slaved and/or clustered. I helped design our networks to withstand failures at the network edge, core, firewall and ISPs layers. From a security perspective, I lead an evaluation project spanning several web security appliances.VMware ESX Clustero Consolidated servers into HP blade centerso Built an iscsi network for two EqualLogic SANs o Configured HP virtual connectGroup Wareo Migrated 400 users from Linux, MySQL, imap and postfix based mail system to exchangeo Configured Microsoft Exchange MTAs and mailbox serverso Wrote Powershell scripts to customize Microsoft list management featureso Built jabber server with Active Directory tie inDomain Migrationo Migrated Linux Samba domain controllers to Active Directory 2008 domain controllersLearning Management Systemso Installed and configured Blackboard LMMS for the corporate training department o Wrote powershell scripts to facilitate onboarding of userso Trained helpdesk to use the bulk enrollment process o Wrote Single Sign On php script to authenticate internal user accounts to an externally hosted Sum Total LMMSHeadquarters WAN Upgradeo Worked on a team to replace the open-source linux routers, which I built in a previous project, with Brocade CERso Added new firewalls and re-wrote the access-listso Built redundant connections from routers to ASAs to core networko Evaluated and configured WAN security appliances o Migrated configuration of Cisco ASAs to Palo Altos

As our company began to grow rapidly, I volunteered to leave the public facing “Systems Engineering” team to help build the basis of an internal, corporate facing systems administration team. Keeping with the company culture of this era in dealer’s history, all architecture and solutions were based on open source solutions. Highlighted Projects: Open Source Network Applianceso Built two solid-state network appliances as an in house, free, Cisco alternative o Built and deployed open source vpn, dhcp, intra-vlan routing, time, and firewall services o Configured auto failover using keepalive in the event of a malfunction o Transparently passed all web/chat traffic to a proxy server for log processingo Configured router to route all web based traffic to an open source Squid proxy server and automate the processing and storage of logs into a MySQL database. o Programmed the auto failover of the proxy in event of a failure to reach external web pagesOpen Source Linux Backup solutiono Replicated the backup’s catalog (databases) to less expensive hardware as a “backup of the backup” o Performance tuned MySQL for faster inserts into databases o Load balanced backups by re-compiling the software to use multiple databases and storage engines o Programmed the offsite migration and encryption of backup files to Amazon cloud storageo Configure “Rancid” as an open source method of extracting and storing network configurations from all Foundry network switchesOpen Source Monitoring server o Built an open source “zenoss” monitoring server to monitor all VT networks and servers. o Built customized alerting rules bases on nagios plugins and snmp probes o Wrote scripts to auto resolve common issues detected by the monitoring system.

I worked on a team of systems engineers tasked with keeping our public facing datacenter operational for 99.999% of the year. This job was heavy on automation through scripting and required an extreme depth of knowledge in Linux. o Build, deploy and maintain Linux and Windows servers in both physical and virtual environments o Troubleshoot java application and MySQL database issues o Provided 24/7 365 server support for service level agreement emergencieso Provide on-call rotational support for critical server failuresHighlighted ProjectServer Monitoring Projecto Install open source server monitoring software (Zenoss) on Linux virtual machines o Install and configure SNMP extensions on all server nodes o Generate commands and templates to probe servers for port checks, disk space, cpu load, MySQL replication stats, apache and java application performance o Generate real time graphs based on performance data o Generate alerting rules to send alerts based on specific metrics to user groups on time schedules

Worked as the primary support contact for one local and two remotes offices. I supported OSX and Windows platforms and worked on several administration projects to increase the efficiency of our department. Highlighted Projects:LINUX & High Availability o Install, configure, research and cost analyze Fedora Core 6 /Red Hat Enterprise Linux as an alternative to OSXo Test, research and propose high availability file and web solution based on virtualization, Coyote Point load balancers and StorNext o Attend VMware training labs and test clustering abilities of ESK servers and VDI thin client desktop distribution.REQUEST TRACKER (RT) TICKET MANAGEMENT SERVER (used to track all tech support requests) o Built with Postfix, Mailgate and alias configuration to allow incoming mail to generate tickets in corresponding ticket queues MOODLE COURSE MANAGEMENT SERVER (to serve as the basis for a cooperate wide intranet) STORAGE AREA NETWORK DESIGN o Initial blue print and planning of a high-definition capable SAN for JDK’s interactive team o Redistribution of DAS Arrays into SAN configuration for both active and archival storage o Attended an advanced XSAN class, where blueprints were built and tested on Apple’s Xserve Raid hardware, the StoreNext file system and Qlogic fiber optic switches.

Team lead and mentor to five helpdesk employees. I designed and implemented a managed OSX client and server architecture using roaming profiles. This spanned five schools and 500 nodes. Introduced automated imaging for both windows and osx clients and tied the windows workstations and servers into Apple’s Open Directory for centralized authentication. I served as the project lead in the district’s first one to one laptop deployment and secured the laptops using mobile profiles and rsync backups. Working with cisco consultants, I helped to overhaul the central office and middle school LAN, departing from a flat network and introducing layer three switches.
