About Me

I'm a Back-End Developer experienced in .NET Core, Golang, Kafka, and Elasticsearch. I've delivered high-revenue e-commerce advertising and fintech payment systems at companies like Hepsiburada and Moka United.

I build and optimize scalable microservices — payment gateways processing cross-border transactions, real-time ad auction pipelines, and event-driven architectures on Kubernetes. I ensure 100% SOX compliance, cut infrastructure costs, and design systems that perform at scale.

On AI Development

I use AI tools as a senior pair-programmer. The architecture, decisions, and quality bar are always mine. AI accelerates — it doesn't replace judgment.
