John returned to the Infrastructure Group of Walton Institute in October 2016. His current role within Walton Institute is as the Technical Lead within the Infrastructure Group.

Prior to this he was working with Cartoon Saloon (a feature-film animation studio based in Kilkenny). While with them he developed a multi-year roadmap of IT infrastucture improvements, and personally orchestrated the first phase of these: a major networking and storage upgrade that had to be completed with zero hours of lost production time. This has since formed the blueprint for Cartoon Saloon’s other ventures, including their new production partnership company, Lighthouse studios.

From November 2015 to April 2016 John was responsible for developing a proof-of-concept network security device. This involved the use of various technologies including AWS, OpenVPN, Ansible, Mikrotik Routers, Raspberry Pi, PHP and the Python language.

From 2013 to mid 2015 he was in a start-up company where he spent quite a bit of time in Europe talking to prospective customers and agents. This included and several weeks testing at Deutsche Telecom labs. This resulted in several customers including Reitlanden BV, Port of Amsterdam, and the German government security services. He was responsible for the design, deployment, comissioning of services across all AWS regions, some custom deploymentsfor specific customers, as well as monitoring and management systems for the entire infrastructure and Level 3 support.

John is a volunteer with Waterford Civil Defence, holding the rank of first officer. He is a radio communications instructor, swiftwater rescue instructor, and a IAA certified SUA (drone) pilot.
