I have 15 years of design experience. In the first 2 years between 2003-2005 after graduation, I have drawn all technical drawings with Autocad that we manufactured. I've designed all site products and organized assembling them. After 2005, I've learned Solidworks and all my designs were 3d after that year. We are manufacturing welded parts and all projects given by the customer in 2d were converted to 3D by myself. After 2009, I also learned ANSYS Structural and after that, I also gave engineering services to customers for the optimization of designs. Lastly, after 2010, I also studied ANSYS Fluent and CFX for fluid dynamics, especially centrifugal fans. For manufacturing, in 2012 I also had a diploma in Welding Engineering and this year I got NDT Magnetic particle and visual test certificate level 2.
