2-Week Rapid MVP Sprint
Overview
Fast-paced cafes and restaurant groups generate thousands of daily transactions across coffee blends, pastries, and lunch items. Managers are too busy on the floor to analyze gross margin shifts, milk expiration curves, or customer churn patterns. We built an autonomous multi-agent platform where specialized LLM agents debate price elasticity, perishable inventory, and customer footfall to deliver verified daily pricing briefs automatically.
Our key engineering goals were to:
- Build a resilient production architecture ensuring zero-downtime reliability.
- Enable real-time transaction synchronization with sub-second latency.
- Design intuitive role-based dashboards empowering users with self-service tools.
- Guarantee strict transactional consistency across all external payment gateways.
Pain Points
Store managers spent 3–4 hours each week manually reconciling POS exports into pricing rules. Promotions were decided purely by intuition rather than ingredient spoilage and demand elasticity.
- Store managers spent 3–4 hours each week manually reconciling POS exports into pricing rules.
- Promotions were decided purely by intuition rather than ingredient spoilage and demand elasticity.
- Traditional LLM prompts suffered from hallucinations and unrealistic discounting proposals.
- No automated execution layer existed to bridge data insights into ready-to-run digital signage promotions.
Research
We built an autonomous multi-agent BI system powered by Groq-accelerated Llama-3-70B models with a strict consensus arbitration loop and automated morning Slack summaries.
Core Architectural Solutions:
- Role-specialized agent architecture: Inventory Analyst, Margin Guardian, Churn Predictor, Promo Strategist, and Executive Judge.
- Strict JSON Schema guardrails with Zod validation ensuring zero hallucinations.
- One-click export directly pushing verified campaigns to digital signage and POS menus.
