What I'm looking for

I’m looking for a software engineering role where I can build microservices and event-driven systems, modernize legacy codebases, and take ownership with strong engineering practices that support continuous improvement.

I’m a software engineer focused on turning complex systems into maintainable, scalable services. I’ve worked across microservices, event-driven backends, and modern frontends, with an emphasis on clean architecture and reliable delivery.

At Yapı Kredi, I contributed to the Nostro project’s transition from monolithic architecture to microservices. I supported database design, requirement analysis, and microservice development, and used AI-assisted development workflows to produce architecture documents and coding guides for faster, more consistent execution.

I also strengthened legacy system modernization by documenting existing flows and improving maintainability for AI Agents. I developed and maintained MKK-related features and provided on-call production support, resolving critical system issues when they mattered most.

Earlier, at Mobiliz, I delivered vehicle tracking, fleet management, and reservation apps using Java Spring Boot and React.js. I built a Kafka-based event-driven project that ingests vehicle info, automates command execution, and reliably handles 35M+ events per hour during peak hours.
