Indie Dev Builds Instagram DM Ordering AI Agent for 7 Sushi Stores Using Claude

An indie developer used Claude Sonnet 4.6 to build an automated Instagram DM ordering system for a 7-chain sushi restaurant. The AI can chat with customers in real-time, introduce the menu, flag allergens, make recommendations, and auto-complete orders, which are then pushed directly to the kitchen POS and CRM. The tech stack includes a SvelteKit frontend, Meta API integration, and pg-boss task queue. By leveraging prompt caching, about 97% of messages hit the cache, drastically reducing API costs per DM. This serves as a fully replicable case study of high-quality AI agent deployment in the physical F&B industry.
