What I'm looking for

I’m looking to build AI-native, event-driven backend platforms—especially for autonomous banking workflows, intelligent document processing, and real-time operational reliability. I want ownership of production-grade architectures with strong observability and maintainability.

I’m a Senior Software Engineer specializing in backend platforms, distributed systems, and AI agent orchestration, with a strong focus on real-time fintech systems, reliability, and observability. I design production-grade architectures using Java and Spring Boot, event-driven microservices, and DDD/Hexagonal Architecture, integrating AI workflows with Kafka-based streaming and clean architecture principles.

I’ve also co-authored graduate research on real-time banking fraud detection, demonstrating sub-200ms processing latency and 96.8% model accuracy with an end-to-end Apache NiFi + Kafka + Airflow pipeline. In my current role at Yapi Kredi Technology, I lead AI agent orchestration initiatives with LangGraph for autonomous banking workflows and architect DDD-based microservices for next-generation digital banking infrastructure; previously at Getir and Siemens, I delivered high-scale product and operational systems and built full-stack industrial and e-commerce software.
