🎯 The Challenge

Selection Friction & Decision Paralysis: Traditional wine e-commerce filters are overwhelming for non-expert buyers who struggle with complex sommelier terminology.

Custom Conversational AI Engine: Training and integrating an LLM capable of accurately understanding domain-specific wine terms, tasting notes, and meal pairings in real-time.

Ground-Up Architecture: Building a high-performance web platform and API infrastructure capable of linking conversational chat outputs directly to live inventory, cart systems, and checkout flows without latency.

🛠️ What We Developed

1. 🏗️ Custom Web Platform (Ground-Up Build)

Designed and engineered a modern, high-performance web application tailored specifically for wine and gastronomy sales.

Built a clean, mobile-first responsive interface with custom product cards, filtering systems, and order management workflows.

2. 🍷 AI Sommelier Engine

Implemented a custom LLM-based recommendation pipeline trained on detailed wine metadata (tasting notes, grape varieties, body, acidity, aging, region, and food pairings).

Enabled natural-language inputs (e.g., "I'm having grilled salmon tonight and need a crisp white wine under $30").

3. 💬 Digital Wine Chat Assistant

Integrated a real-time interactive chat module with streaming responses (via WebSockets).

Embedded interactive product cards directly inside the chat interface, allowing users to add AI-recommended bottles to their cart with one click.

4. ⚡ Seamless E-Commerce & Inventory Integration

Connected the AI assistant directly to real-time database stock levels, pricing tiers, and checkout pipelines.
