Expand Current Company
My employer is a provider of electronic commerce and payment solutions. The company’s portfolio includes merchant transaction processing services; credit, debit, private-label, gift, payroll and other prepaid card offerings; fraud protection and authentication solutions; electronic check acceptance services; as well as Internet commerce, mobile payment solutions and PIN-secured debit acceptance at ATM and retail locations.
In my role as Enterprise IT Security Architect:
My focus has been directed towards the architecture and design of perimeter information and networking security systems and services, which has allowed me to take a step back and analyze the security and threat landscape, how it relates to the overall security posture of the enterprise, and utilize that information to design successful and sustainable solutions and services.
In my role as Security Engineer II:
I wore several hats that span various “silo’s” across the security organization, primarily responsible for providing research, design and engineering support of enterprise class information and network security solutions.
Under one hat, I was responsible for firewall, proxy, IDS compliance and audit reviews, security reviews of publicly accessible architecture and public facing payment systems. I also had a hand in providing an security knowledge escalation point for, and training/mentoring of, the team supporting pre-change security review process for firewall/proxy/sslvpn/etc requests.
Under another hat, I ran the corporate advanced malware protection service with a heavy emphasis on shared threat intelligence throughout our deployed security toolsets to identify, and help various teams respond to malicious events in our environment with speed, agility and accuracy.
I worked tightly with security operations/monitoring and cyber threat intelligence groups to ensure that detection tools are in in the correct locations with the correct visibility, and that they are tuned correctly to provide the highest amount of actionable alert data with the lowest amount of background noise or false positives.

I was a part of this program as an FST for 3 years.
My responsibilities were for the operation and maintenance of one of twelve, Herzog-built and owned, ballast trains leased to UP, BNSF and NSX railroad companies. The train I operated used a patented programmable linear unloading system, P.L.U.S., and computer guidance via pre-programmed surveys linked to global positioning satellites to spread ballast at high speeds over the railway. This method of ballast spreading increased safety by reducing the number of ground personnel required to zero. Another benefit to this method is that, with no required ground personnel, ballast can to be spread over the railway 24hrs a day.
In addition to operating the train during ballast spreading, my responsibilities included the maintenance of each ballast rail car and their respective systems on the train. The on-board systems required scheduled maintenance on industrial batteries, ballast spread door hydraulics, hardened electronics, and two 4 cylinder diesel generators to maintain charging of a bank of batteries in each rail car. All components were required to operate at the highest level to comply with rail service company regulations.
