EXPERTISE
BIO
My relationship with Information Technology goes back to before my undergraduate education. Even when I was not familiar with software yet, I spent my summer months working in Technical Service departments of various institutions for short periods. In this process, I saw that my social and technical skills were prone to the field of engineering and I chose Industrial Engineering, which is a field where I can integrate my skills in these fields in my education life. I have built my professional career on these skills. In addition to my business life, I continue to work as a hobby and include software-based works such as RPA projects and Web site development projects.
