As a mechanical engineer (M. Sc.), with 12-year-experience in the field of heavy-duty vehicle industry (both in production and after-sales services phases), due to the positions to which I was assigned, I carried out various activities in many fields such as design, product development, planning, production, purchasing, project management, after-sales technical support, spare parts, administrative issues, marketing operations and I had chance to make face-to-face contact with the hundreds of customers and leading OEMs in the market, and created solutions from a technical viewpoint.
