I build and run the internal automation stack for an 8-figure multi-channel ecommerce operator: 26,000+ SKUs across Amazon, Walmart, eBay, Shopify and SellerCloud, with QuickBooks Online as the accounting system. Started as a price analyst on the catalog, then moved into building the automation. A dozen of those automations now run in production, unattended. Accounts payable: vendor invoices parsed, matched to purchase orders, checked against vendor price lists, and entered into QuickBooks behind an approval gate and an audit trail. 1,027 invoice line items reconciled cent exact. 32 bills entered in a single unsupervised business day, zero wrong actions. Inventory: hourly oversell and stockout monitoring. The first hour surfaced 22,849 exceptions, 184 of them oversold with customer orders already taken. Restock forecasting: 5,165 SKUs analyzed every morning, reorder recommendations grouped by urgency, read off the ERP's own velocity windows instead of a homegrown guess. Demand alerts: daily detection of products whose sales collapse against the same day last week, which is how silently broken listings get caught before they cost a month of revenue. Customer communications: a Slack to Shopify to helpdesk automation that replaced a broken vendor workflow which had silently stranded roughly 70 customers over two weeks. Cost writeback: supplier cost changes written back into the ERP behind a price-change ceiling, idempotency checks and a kill switch. An audit of the manual process it replaced found humans were silently dropping 12% of their own updates. Everything ships like production software: 1,189 automated tests, an audit trail on every action, and an off switch. Also diagnosed and fixed a store-wide image defect across 9,386 Shopify collection pages that was feeding Google the wrong thumbnails.
