Inventory Ledger and Invoice Extraction. Barcode-driven parts custody for an office-supplies company: every part moves through an append-only ledger (purchase in, issue, install or return), so its current location and holder can be rebuilt from the event log at any time. Built with Flask and SQLite and deployed on the office network over Tailscale. For the same client I built an LLM pipeline that extracts vendor, GST number, line items and taxes from supplier invoices into clean CSV, and a Next.js B2B product catalog.
