Production Planner / Buyer at LightPath Technologies who corrected material planning logic and reduced cost per lens.

Poland

Message

At LightPath Technologies, I managed purchasing and production planning in Visual ERP, aligning purchase orders, work orders, and schedules with customer demand. I investigated material shortages by comparing planning assumptions with customer call-offs and consumption, then corrected planning logic.

I coordinated suppliers, Production, and Sales on bottlenecks and delivery commitments. Structured supplier follow-up improved order-confirmation turnaround to an average of 2 days.

I also identified BOM and material-demand discrepancies and coordinated data corrections. By optimizing coating, purchasing, and production schedules, I reduced cost per lens from approximately $4.48–$7.28 to $1.40–$1.60.

Earlier, at Acumen International, I managed international employer-of-record projects and, as a Senior Account Manager, led 2–4 Account Managers. My work included coordinating clients, providers, and internal operations, reviewing costs and invoices, and reporting operational risks and corrective actions.
