Forecasting and pricing for after-sales supply chains

160,000 SKUs, 15 dealers, Dynamics 365 — rolling forecasts, pricing integrity and commercial reporting.

Analyst with an applied mathematics background, translating commercial requirements into rolling forecasts, pricing models and customer segmentation models.

At Saracakis Group I own pricing data integrity and ERP master data (Microsoft Dynamics 365) across a 160,000-SKU multi-brand after-sales parts catalogue serving 15 dealers and key accounts, and deliver VP-level reporting on turnover, gross profit and GPM % for a business averaging ~€300K monthly turnover.

I'm completing a Diploma in Applied Mathematics & Physical Sciences at NTUA part-time alongside full-time employment, with a focus on ops, supply chain and data-adjacent work.
