About the Company

I am an exceptional, ingenious Systems Engineer with over 20 years of general computer experience, the last 10 of which have been in large, 24x7 Enterprise environments. If you are in need of someone that is personable, self-motivated, and can hit the ground running, I am your perfect candidate.
Service Description
Providing excellence and efficiency with Systems Engineering tasks, including heavy use of Open Source solutions to save you time and money. Some of my favorite enterprise capable Open Source solutions include Keepalived, HAProxy, NGINX, Kerio, OTRS, OpenFire, and OpenVPN.

Employment
Teletech Holdings
Principal Systems Engineer
2007 - 2010
Our three person UNIX team supports over 300 servers globally, from design through production steady state. The heterogeneous environment utilizes AIX, Solaris, and RedHat in varying capacities. We support Oracle 9i and 10g on both AIX and Linux, as well as many different home-grown applications on Linux and Solaris. Here are some of my major contributions and successes: * PCI & SOX Compliance The company has been through two major PCI audits in the last two years. My security expertise and diligent documentation have been instrumental in passing these audits with flying colors. I personally ensured that critical servers in the DMZ were updated to take advantage of the robust security SELinux provides. * Server Consolidation & Cost Savings Supporting a global 24x7 heterogeneous environment with only three Systems Engineers fostered the need to consolidate and simplify. We've utilized VMWare, Solaris Containers, and migrated Oracle from large, expensive AIX servers to small Dell servers running Linux. The power & cost savings have been enormous. * Global Standards & Cooperation The UNIX team works closely with IT departments around the world. I have personally taken extra steps to work cooperatively with these groups to provide more efficient and effective support for the UNIX environment. The operational documentation & procedures I've written are currently in use globally. * Adoption of Enterprise Capable Open Source software I've personally saved the company over $100,000.00 and three head count by utilizing Open Source technology instead of expensive dedicated hardware. Technologies include Keepalived, HAProxy, NGINX, OTRS, Kerio, and OpenFire.
Cendant Corporation
Senior Systems Engineer
2005 - 2007
Cendant was previously known as Galileo, and more recently as Travelport. I was part of the Hardware Configuration Management (HCM) team. We were responsible for engineering infrastructure and procedures for many different internal development projects that ultimately end up in the 24x7 production environment. HCM was responsible for the entire process from design through steady-state production support. We wrote procedural documentation and training for production hand-off, and provided after hours support during re-imaging and new code rollouts. We also provided tier 3 and tier 4 support for the development & performance lab, and were frequently consulted to assist with production issues. Here are some of my major contributions and successes while at Cendant: • $120,000 Per Month Cost Savings The realized goal of the Dynamic Connection Construction (DCC) project was to save over 1.4 Million dollars per year by moving a critical, travel related data processing function from a costly mainframe to a horizontally scalable, load-balanced Linux cluster. I personally developed the framework, scripts, procedures and documentation for the DCC application and received special recognition for my work. • Offered Lead Systems Engineering Role in China Due to my proven work ethic and outstanding engineering track record, I was offered the Lead Systems Engineering role in a data center duplication effort. Cendant was approached to build out a Shared Travel Platform (STP) environment in China to accommodate the travel rush during the Beijing 2008 Olympic Games. Unfortunately Cendant did not win the contract. • Increased Maintenance Efficiency & Reduced Downtime I personally developed, documented, and maintained a custom process to update firmware and BIOS for over 500 IBM X-Series servers, HS20 Blades, and Blade Centers. The entire automated process was scripted using Open Source software, and was easily administered remotely. This process allowed a single Engineer maintain the same amount of servers that would normally require an entire team. • Rapid, Parallel Bare-Metal Provisioning The process and procedures I developed allowed for rapid, parallel bare-metal provisioning, which increased efficiency and reduced production change management windows dramatically. Using Open Source tools and custom scripts, we were able to re-image many application servers in parallel. The automated process took a server from a blank hard drive to taking production traffic in under 10 minutes.
Volt Technical Services @Agilent
Senior UNIX/Linux Systems Engineer
2004 - 2005
I provided ongoing core administration, security administration, systems engineering and “deep support” for the UNIX/Linux Competency Center (UNIX-CC) of Agilent Technologies’ IT Services Hosting Organization and associated clients of VMC Consulting Corporation. Due to Agilent’s world-wide presence, I worked closely with business partners and colleagues in many different time zones. The team provided UNIX engineering services to initiatives and projects requiring in depth knowledge of UNIX processes, hardware solutions, software solutions, and associated standards. We met multiple technical internal project requirements and timelines while supporting diverse client organizations with varying and unique requirements. Here are some of my major contributions and successes while at Agilent: • Automated Account Administration Agilent management was unfortunately opposed to commonly used, convenient, centralized authentication such as NIS. This decision left the UNIX team with the huge undertaking of developing, maintaining and actively monitoring automated scripts to administer and audit hundreds of user accounts on over 850 UNIX servers. I personally assisted with the development and ongoing administration of those automated scripts • Security Auditing The UNIX team utilized Power Broker for security monitoring. I was responsible for console replay investigations whenever there was a security incident. I also personally assisted with development and administration of the security scripts that checked for password complexity, expired passwords, and orphaned user accounts.
Pixxures
Senior Systems Engineer
2001 - 2004
Responsible for complete administration of more than 50 Linux workstation and servers, and 10 Windows servers. Administration and up-keep included rebuilding the kernel to support the newest hardware and software available, while maintaining maximum production stability. I also administered the internal firewall, DNS, NIS, mail and web servers, as well as the Windows 2000 machines used by sales and marketing. Here are some of my major contributions and successes while at Pixxures: • Rapid Assimilation & Transition to Linux Prior to working for Pixxures, my Linux exposure was minimal. I was able to quickly dive in and become a Linux guru within weeks. Within my first month alone I was able to solve a persistent production problem that the existing UNIX Lead/Manager had been unable to solve. • Overcoming Technology Challenges The GIS processes at Pixxures required bleeding edge technology in order to be efficient and profitable. Even with limited applicable Linux experience, I was able to utilize my strong analytical troubleshooting skills and tenacity to successfully solve those technical challenges. I utilized my ingenuity to overcome uncommon issues with unstable copper gigabit ethernet, USB & Firewire drivers, as well as the need for massive amounts of hot-swappable storage.
US West/QWest Communications
Senior UNIX Engineer
1998 - 2001
Part of a large enterprise team responsible for several hundred Solaris and Linux servers. Wrote a web-based CMDB that utilized Perl scripts on the back end to collect various important inventory and server information. This stint was a contract role, and QWest's full time offer was no where near my contract rate, forcing me to seek employment elsewhere.
IBM Global Services
Desktop/UNIX Systems Engineer
1997 - 1998
I started at IBM as a desktop engineer, and quickly moved into a UNIX Systems Engineer position within 6 months. Our team was responsible for over 100 Enterprise HP-UX based UNIX systems for a very large client of IBM. Unfortunately I ended up stuck in the midnight shift and wasn't learning or performing enough tasks to keep me interested. I finally got tired of many false promises and ended up finding a day shift job with US West just a couple of months later.
