01 — Voice agent
An AI receptionist that takes fast-food orders over the phone
Context
During the rush, nobody in the kitchen has time to pick up the phone. Every missed call is a lost order.
My role
End-to-end design and development with Claude Code: voice agent, business logic, database and kitchen dashboard.
- Voice agent that answers calls and takes the order and the customer's first name
- Order shown instantly on a kitchen tablet (real time)
- One tap on “ready” from the cook, and the customer gets a text message
- Design rule: the LLM decides nothing. Products, options, prices and totals are validated in the database, never made up by the AI
82 automated business-rule checks, plus call and rush-hour simulators.
