Ghilman Ghariy

As a Nanotechnology Engineering graduate from Airlangga University, I have developed strong analytical and problem-solving skills through hands-on experience in materials research and characterization, enabling me to address complex technical challenges effectively. I have also been actively involved in student organizations in leadership roles, strengthening my teamwork and management abilities. In addition, I have completed ISO-related and basic occupational health and safety training to enhance my quality awareness and industry readiness.
