Experience/Brief History
Originally began working part time in the industry whilst pursuing other studies but after a few years decided to make a career out of it and haven’t looked back since. Have been lucky enough to have had the chance to work in many different aspects of the industry, from small industrial machines to the larger power generation and mining machinery, in many countries all over the world. I have recently also been heavily involved in getting the company up to standard to receive their OHS Certification.
