    Was added to a PCI firewall deployment at FirstData that was months old with a looming deadline. After scoping out the work required and how the progress was proceeding, I determined that drastic action was required to meet the deadline that was 8 weeks away. Using OS tools, I built a framework that could determine what policies were needed, and based on log analysis and normalization of collected data, my framework was able to define the policy across 9 firewall clusters and enabled us to deploy changes inside of 6 weeks, meeting the PCI deadline with 2 weeks to spare.
