@onurmertnemis

Technical Product Owner at Türk Telekom shaping backend APIs and cloud platforms, including a RAG assistant architecture on H100 GPUs.

At Türk Telekom, I set product direction and own backlogs for three concurrent products: e-Invoice, DCIM and the Management Dashboard. I write technical user stories and acceptance criteria, specify REST API endpoints for a Java/Spring Boot team, and coordinate testing and releases.

I designed REST integration mappings across DCIM, Siebel CRM, billing and inventory, and oversaw migration validation with 2,000+ test cases. I also designed a RAG architecture for an enterprise chatbot on H100 GPUs and lead service design for a Model-as-a-Service platform on Red Hat OpenShift AI.
