What I'm looking for

I’m looking for a demand/supply planning role where I can turn sales and inventory data into practical forecasts and execution, using Excel tools, Power BI, and SAP to improve stock efficiency, service levels, and measurable business results.

I’m an International Demand Planning and Supply Planning specialist based in Turkey, combining historical sales analysis with inventory optimization to improve stock efficiency and reduce stockout risk. I’ve managed end-to-end planning and operational workflows across e-commerce and international channels.

In my role for Bosch, I developed and managed demand planning for e-commerce channels by analyzing historical sales data and optimizing inventory. I also coordinated consignment processes and reverse logistics, achieving a minimum 2.5x year-over-year increase in Bosch’s monthly sales.

I’m comfortable working at model-color-size detail using repeat (RPT) and substitute product order planning, and I build planning tools in Excel (including macros and formulas) to increase operational efficiency. I’ve supported planning through SAP (including phase-in products) and dashboards/visualizations with Power BI.
