Message

At Enerjisa Enerji, I managed revenue assurance operations focused on reducing financial leakage and improving operational efficiency. I developed predictive models for revenue risk and built executive KPI dashboards and automated controls.

Earlier at Enerjisa Enerji, I established credit risk operations for free market electricity customers and developed analytical risk frameworks. I also implemented credit bureau integration initiatives for energy market customer risk assessment.

At GarantiBBVA, I developed business intelligence and analytical reporting systems for banking operations, including predictive analytics using data from more than 3,000 system tables. My earlier research work at GfK Turkey and Konsensus Consultancy included consumer behavior analysis, forecasting, and survey research.
