A bilingual Meta Llama–powered chat agent that lets Latino corner shops take orders, run loyalty, and track pedidos — no app, no POS, just chat.

Problem: Neighborhood Latino shops — panaderías, cafecitos, tienditas — run on WhatsApp messages, phone calls and paper. Orders get lost, Spanish/Spanglish customers aren't served by English-only ordering tools, and owners can't afford POS/loyalty platforms built for chains.

Solution: La Esquina Shop Agent is a WhatsApp-style chat ordering agent. Customers write naturally in Spanish, English or Spanglish ("quiero 2 pastelitos de pollo y un café con leche"); the agent understands, builds the cart, confirms, checks out with just a name, and awards loyalty points. The owner opens a PIN-protected portal on their phone to see incoming orders and status. Menu, prices and totals are computed server-side, so the AI can never invent a price.

Demo: https://shopagent.velvetgeaux.com (owner portal /owner, demo PIN 2026)
Tech stack: Meta Llama 3.3 70B (Workers AI) · Cloudflare Workers · Durable Objects (SQLite) · static HTML/JS frontend · Wrangler.
Challenges: Keeping a 70B model fast and cheap at the edge; preventing price hallucination by separating LLM understanding from deterministic cart math; natural Spanglish handling.
What's next: Real WhatsApp Business channel, per-shop menus via owner chat, pickup notifications, multi-location.
