AI-Powered WhatsApp Restaurant Ordering

An AI-powered WhatsApp ordering system that handles customer conversations, understands ordering intent, checks restaurant information, validates orders, and stores order data through an automated workflow.

I built an automated WhatsApp workflow where incoming customer messages are processed by an AI Agent. The agent uses Google Gemini for reasoning, memory for conversational context, and connected tools to retrieve inventory and FAQs and store confirmed orders.

What it is

I built an AI-powered WhatsApp restaurant ordering system that turns customer messages into structured orders through an automated AI agent workflow. The system connects WhatsApp, Google Gemini, conversational memory, inventory data, FAQs, and order storage into a single workflow.

The problem it solves

Restaurant staff often have to manually respond to customer messages, answer repetitive questions, check availability, and record orders. This creates unnecessary workload and can lead to slower responses or inconsistent order handling.

How it works

  1. WhatsApp message trigger

  2. AI-powered customer conversation

  3. Google Gemini chat model

  4. Contextual conversation memory

  5. Dynamic inventory lookup

  6. FAQ retrieval

  7. Order validation and processing

  8. Automated WhatsApp responses

  9. Order data storage

  10. End-to-end workflow automation

The engineering focus

I built an automated WhatsApp workflow where incoming customer messages are processed by an AI Agent. The agent uses Google Gemini for reasoning, memory for conversational context, and connected tools to retrieve inventory and FAQs and store confirmed orders.
