Darrin has a rare combination of technical support, training and commercial leadership experience, having supported ANSYS-CFX deployments across Australasia and led technical teams to deliver client-focused CFD solutions. He also brings product distribution and partnership experience through Applied CCM’s Pointwise representation, and a recent broadening into cyber security and business law studies that sharpen his risk-aware, commercially minded approach.
