Paul was one of the founders of Global-Roam in February 2000. He is currently the CEO of the company and the principal author of WattClarity.

Before co-founding the company, Paul worked as a Mechanical Engineer for the Queensland Electricity Commission in the early 1990s. He also gained international experience in Japan, the United States, Canada, the UK, and Argentina as part of his ES Cornwall Memorial Scholarship.
