Zeynep Sila Y.

Inventory & Demand Planning Analyst | StockIQ, Excel, Power BI, SQL

Analysed $6.1M of inventory and a $43.7M order book for a US distributor on StockIQ; found $1.53M of projected excess sitting in still-cancellable POs. The client's 5-star review on this profile is about that implementation. I am an industrial engineer and business analyst (İzmir, Türkiye) who turns planning-system exports into decisions: 1. Inventory and demand planning: consolidate ERP/StockIQ/Excel exports into one item-site-customer model; ABC/XYZ, safety stock, reorder points, excess and stockout risk; a 12-item action plan with owners and dates. 2. Excel, VBA and Power BI reporting: automated periodic reports (SAP finance data at an aerospace manufacturer), traceable formula-based models with a source-and-method tab on every sheet. 3. Business analysis: requirements, process documentation, UAT coordination, all in English, in an Agile cadence with software teams. Tools: Excel (advanced, VBA, Power Query), Power BI (DAX), SQL, Python (pandas), SAP, StockIQ, Jira. Send a sample export and I will return a quick excess/stockout snapshot within 24 hours, before we sign.
