• Created a scalable, standard’s based enterprise process for software patching and version control.
• Broke down multiple company silos. Example: requested access to corporate analytics system to compare customer reported issues with the operations team’s issues list. This data was used to set priorities based on customer value, revenue generation, and loss prevention. One of the identified items saved over $300,000/month.
• Helped create an automated intrusion detection system that required dissecting a proprietary networking protocol communicating with an IBM z/OS based mainframe.
• Selected by Sabre Vice-President to be the technical representative for the SOX compliance team as part of Sabre’s preparation to become a publicly traded company. This project required software library and other architectural changes to multiple Sabre systems.
