Cover image for Inventory Ledger and Invoice Extraction.
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.

Cover image for Custom Restaurant POS. A restaurant
Custom Restaurant POS. A restaurant operations stack for a quick-service restaurant in Noida: touch-screen kiosk ordering with Razorpay payments, a kitchen display and order management, a customer queue screen and a CMS-backed website, running on-premise. The POS is offline-first, so orders queue locally and reconcile when the connection returns, and service keeps running through network outages. Built with TypeScript, Next.js, SQLite and Drizzle in a pnpm and Turborepo monorepo.
