What I'm looking for

I'm looking for roles where I can build modern backend architectures and work on LLM and AI integrations such as RAG, while pushing engineering boundaries.

At CİM GAMES, I worked as a Software Developer intern, architecting and maintaining backend modules with .NET and C#. I used Clean Architecture and CQRS/MediatR patterns.

I also designed internal systems with SQL Server and Entity Framework Core, and containerized services with Docker.

On my ZeroCopyRagEngine project, I designed a text chunking algorithm that measured zero allocations and ran 61 times faster than the standard string.Split approach in BenchmarkDotNet.

As a freelance Software Engineer, I designed and developed onmediastudio.com, a production-ready Turkish- and English-language studio site with Next.js, iyzico payment integration, SEO optimization, and responsive UI. I also delivered e-commerce solutions for clients, including a jewelry retailer, and handled projects from requirements through deployment and ongoing maintenance.
