Master's degree, Chemical and petrochemical engineering

Lebanon

As a passionate and detail-oriented Chemical and Petrochemical Engineering student at Saint Joseph University of Beirut, I bring a solid academic foundation and diverse hands-on experience across the chemical, petrochemical, petroleum, plastics, cosmetics, and food industries. My journey has allowed me to design and simulate industrial processes, conduct quality control testing, and apply engineering principles to real-world challenges. Through internships at leading companies such as Baalbaki Chemical Industries, Hypco, MEDCO, Pandaplast, SAGA Cosmetics, and Center Jdita, I gained exposure to process simulation, petroleum operations, plastic molding techniques, cosmetics formulation, and dairy production. My technical toolkit includes Aspen HYSYS, Matlab, Python, IBM SPSS, and Microsoft Office, along with strong expertise in process optimization, safety standards, and sustainability practices. Motivated by a strong interest in industrial innovation and sustainable development, I strive to contribute to impactful projects in process design, operational improvement, and R&D. Known for being analytical, fast-learning, and highly committed, I thrive in multidisciplinary environments where I can continuously grow, collaborate, and deliver value.
