This article provides real-world insights into building practical AI systems for operational efficiency in a restaurant business.
Key Points
- 1Moved the AI interface from a web app to WhatsApp, leading to a 10x increase in daily active users
- 2Developed a natural language to SQL query engine with 94% accuracy on 23 KPI queries

- 4Used Whisper for voice-to-text transcription of shift handoff notes with prompt engineering to reduce hallucinations
Details
The author built an end-to-end AI operations system for a 236-employee restaurant chain over 18 months. Key components include a natural language to SQL query engine with 94% accuracy, a Retrieval Augmented Generation (RAG) system to handle HR and policy questions that reduced tickets by 40%, and a voice-to-text transcription system for shift handoff notes using Whisper. The author emphasizes the importance of minimizing friction for end-users, with the key insight being that employees want answers in the tools they already use (e.g., moving the interface to WhatsApp). Technical approaches include using intent detection and query templates instead of free-form SQL generation, as well as prompt engineering to reduce hallucinations in the voice transcription system.
