  • Verifone (Melbourne, Australia)
    • Estate Management Architect
      Mar 2015 - Oct 2018 · 3 yrs 8 mos

      Over time and via acquisition Verifone ended up with a large number of Estate Management Systems used to manage fleets of Card Acceptance devices. These operated either as managed services or as Customer owned and operated. As the global architect I worked on strategies that would allow for consolidation to one favoured solution - VerifoneHQ. Primarily this involved feature development within VerifoneHQ but in many cases involved working with various regions so that they could integrate with and move their Payment Solution to VerifoneHQ. With more than 600,000 devices under management as a Cloud based service and plans to deploy up to 25M replacement devices with VerifoneHQ many activities revolved around performance and scalability. Working with Cloud Services such as AWS and Akamai provided for the scalability needed, which I balanced with the security needed to ensure PCI Compliance could be maintained.
