With 18 years of experience in decarbonization projects, green hydrogen, and Power-to-X technologies (including green H₂, green ammonia, e-methanol, SAF, among others), I have worked at leading companies such as Voltalia, CHEMTECH/SIEMENS, AMEC-KROMAV, and SENAI CIMATEC. I specialize in the development, planning, and management of multidisciplinary projects from concept through implementation and operation. My work is driven by sustainability, energy efficiency, and technological innovation. Throughout my career, I have gained expertise in managing complex projects using agile methodologies and conducting comprehensive techno-economic and financial feasibility analyses. I have also coordinated pilot plants and led centers of excellence, consistently aiming to optimize processes and integrate emerging technologies to support the energy transition.
