I graduated from Karabük University, Department of Computer Engineering.

I have been working as a Full Stack developer and Java developer around 5 years.

My goal is to work in companies that produce projects using technologies in the fields of computer engineering.

I also continue to share many of my sample works on my GitHub account.

I am constantly working to make life easier and trying to find solutions to common problems of people.

I’m currently learning client-side technologies by using especially GitHub and StackOverflow.
