At Belsoft Bilişim, I designed, developed, and maintained enterprise software components using C#/.NET and SQL Server. I also analyzed system performance, identified bottlenecks, and implemented optimizations.

At Turkcell İletişim Hizmetleri A.Ş. (IT Department), I contributed to Java back-end microservice development. I designed REST APIs and integrated endpoints, then tested them with Postman.

As a Software Development Intern at Belsoft Bilişim Sistemleri, I developed enterprise web application modules and CRUD operations with ASP.NET MVC. I also designed relational database schemas, stored procedures, and views on Microsoft SQL Server.

I’m a Karadeniz Technical University Software Engineering graduate with project experience in Kotlin and Android, including MVVM, Hilt, Room, and Retrofit. My background also includes web and back-end development with Java, C#/.NET, and SQL.
