Aalborg SØ
Summary
Passionate process engineer with over eleven years of experience in design of Water Treatment Plants (WTP), Thermal Energy Storage, membrane desalination, electro-deionisation, and industrial water/wastewater recycling systems for the Power and Energy sectors. I hold a master’s degree in chemical engineering and have expertise in both basic and detailed design engineering for energy storage and water treatment systems within startups and EPC companies. I have delivered multiple water treatment and reclamation projects, as well as research projects at university and in petrochemical industries. Over the past six years, my focus has been on FEED, detailed design engineering, consultation, as well as supervision for commissioning and operation. I am proactive, solutions-oriented, and dedicated to advancing my skills in advanced process systems and green energy for sustainable process design.
