Süleyman Arif Karakılıç

Backend‑Focused Full Stack Developer

Who am I?

Hi, I am Arif.

I graduated from Sakarya University (Computer Engineering, GPA 3.09) in July 2024. I focus on backend and database‑oriented development with JavaScript/TypeScript, C#, Node.js, Express.js and .NET. My projects and internships gave me solid experience in REST/gRPC API design, containerization, database management and server‑side optimization. I also built IDE extensions for VS Code and Visual Studio 2022. I enjoy designing efficient, scalable and secure server solutions. I aim to grow as a backend & database developer in innovative teams.
