Chief Executive Officer

DXC Technology

Recruited to return to Australia as Chief Technology Officer for NYSE-listed DXC Technology, formerly Computer Sciences Corporation (CSC). Served on the Senior Leadership Team and oversaw all technical aspects of the regional business, including the establishment of a distributed team of 10 specialist CTOs. Established the Sydney Innovation Centre and a global network of six such facilities spanning London, Paris, Tokyo, Singapore, and Washington DC. Contributed to the SLT's overall strategy for the $430m acquisition and integration of UXC, setting the stage for the global $26bn spin-merger with HP ES to form DXC Technology.

Elevated to Director of Labs in a global role based in Singapore, where I led a complex, hybrid organisation of over 100 developers—both directly managed and matrixed from other units—across eight R&D hubs. Supervised managers of managers and specialised teams, each focusing on emerging technologies including artificial intelligence, computer vision & voice, drones & robotics, IoT, 3D printing, blockchain, and quantum computing. Introduced 'design engineering' and delivered 'concept to cash' innovation using Agile/SAFe methodologies, utilising lab innovations to drive digital transformation of both customers and offerings, as well as refreshing and refocusing the company’s global workforce of approximately 140,000. Also stewarded IP workstreams through critical M&A transactions, including a $2bn acquisition and a $5bn divestment.

Equinix

Joined Equinix from Google, having worked with them as a supplier, to help them understand the changing needs of large enterprise and cloud providers, tailor products & services accordingly and create a strategy to further expand the largest and fastest growing vertical.

Introduced and advocated the cloud exchange concept, and built a cloud ecosystem around it — a critical mass of best-of-breed cloud providers running on Platform Equinix (which consists of 200+ datacenters in dozens of markets), available through the Equnix Marketplace and accessible via Equinix's various interconnectivity services.

Joined Google ostensibly to work on their Ganeti-based "private cloud" infrastructure, but was allocated to the global tape backup program as the team’s technical program manager.

Worked on the rapid expansion of the program, enhancement of the hardware & software systems, research & development, off-line & near-line storage, security and vendor relations (RFIs, performance management, contracts, payments, etc). Site surveyed all of the Google-owned datacenters in production at the time and initiated expansion projects at each of them.

As Cloud Standards Lead I worked with Vint Cerf and his team on the development and promotion of open standards in cloud computing by way of internal & external events & awards, which I organised and/or attended.

Subsequently completed the following courses with them:
 - Data Engineering, Big Data, and Machine Learning on GCP Specialization
 - Site Reliability Engineering: Measuring and Managing Reliability
 - Serverless Machine Learning with Tensorflow on Google Cloud Platform
 - Serverless Data Analysis with Google BigQuery and Cloud Dataflow
