The Overview
Project context & goals
An admin dashboard and an AI-first WhatsApp ordering bot for the food business Dapoer Mami Fasola.
Customers order from Dapoer Mami Fasola over WhatsApp. The order bot receives their messages through a self-hosted WhatsApp gateway, reads each order with Gemini on Vertex AI, falling back to OpenRouter, and stores it in PostgreSQL. The menu can be changed straight from WhatsApp.
Fasola Finance is the owner's side: today's revenue, orders, expenses, and profit; order status and payment changes guarded with optimistic concurrency against the bot's own writes; menu and expense management; sales reports; and the bot's health, pairing QR code, handoff inbox, and logs. Both run as systemd services on Azure and share one database under a written ownership contract.
