Supply Chain Manager | Inventory & Logistics for 7-8 Figure Brands

I work with private label and DTC brands doing $1M–$10M who've outgrown spreadsheet inventory management but aren't ready for a full-time supply chain management hire. If you're scaling on Amazon FBA, Shopify, or both, and stockouts, cash traps, or supplier chaos are costing you rankings and revenue, that's exactly what I solve. Here's what typically happens before brands bring me in: reorder timing is reactive, safety stock is guesswork, freight delays cause panic POs, and capital sits locked in slow-moving SKUs while your best sellers go out of stock. The cost isn't just the lost sale, it's the BSR drop, the ad spend wasted on recovery, and the 60-90 days it takes to claw back ranking. What I do: → Demand forecasting adjusted for lead-time variability, freight risk, and capital exposure → PO planning & placement with dynamic reorder timing (not static reorder points) → Logistics Management & Supplier coordination across China, US, and multi-country sourcing → FBA + 3PL + warehouse inventory synchronization → Cash flow modeling to prevent overstock while maintaining in-stock rates → Full operational system builds: dashboards, SOPs, reporting cadences Track record: - Managed $2M+ in inventory value across multi-warehouse operations (US, Turkey, Australia) - 40% reduction in stockout events, 97% inventory accuracy, 82%→96% on-time delivery - Built forecasting systems from scratch for brands with 30/60/90/120-day planning horizons - 20+ ecommerce brands served | 94% Job Success | Top Rated Plus I operate as your embedded supply chain function, not a task executor. I build the system, run it, and hand you weekly decision-ready reports so you can focus on growth instead of firefighting inventory. Open to a quick call to assess fit. Send me a message with your current SKU count, primary sales channel, and biggest operational pain point.
