About

With diverse experience in financial management and project cost control, I bring a solutions-oriented approach to McDermott International, Ltd. Currently, I focus on overseeing cost control processes for two large-scale 2GW HVDC megaprojects, leveraging my expertise in budget monitoring, variance analysis, and Cost-to-Completion forecasting. My goal is to drive financial transparency and alignment while supporting organizational growth through compliance with GPCA and US GAAP standards. I am motivated by the opportunity to enhance decision-making reliability and foster a culture of operational excellence within my team. At McDermott, I contribute to integrated financial reporting, ensuring data alignment across systems to enable clear, actionable insights. Previously, as Financial Controller at Basic-Fit, I improved financial processes by driving automation initiatives and enhancing data accuracy.
