Multi-Format Accounts Payable & AI Invoice Extraction Pipeline Designed and deployed an automated AP ingestion pipeline capable of handling scanned receipts, PDF invoices, and email attachments. The workflow normalizes file binaries, routes by media type, and uses multimodal AI vision to extract invoice numbers, line items, and totals. It includes dynamic mathematical validation logic (cross-checking extracted line items against parsed grand totals) with an automated exception-handling branch routing flagged docs to human review via Slack.
