Orders not reaching your 3PL? Inventory out of sync and overselling on Amazon? Tracking never making it back to the marketplace?
I build and repair the API integrations that move data between your sales channels and your fulfillment system.

WHAT I BUILD
Order sync from marketplace to WMS, with SKU mapping and multi-warehouse routing
Real-time inventory sync to stop overselling
Shipment tracking and ASN flowing back to the channel
Fulfillment webhooks with retries and error handling, so orders never fail silently
Repairs on half-built or failing integrations
BACKGROUND
