AURA – Agentic Omnichannel Retail Orchestration System

Inspiration

The idea for AURA began with a simple but powerful moment — watching my grandmother struggle to shop online. Every platform was in English, navigation was confusing, and eventually she gave up. This highlighted a harsh reality:

90\% of Indians are excluded from e-commerce due to language barriers.

At the same time, a local shopkeeper near my home was managing two disconnected systems — one for his physical store and another for online orders. He spent hours manually syncing inventory and frequently made costly mistakes.

These real-world problems inspired AURA — an inclusive e-commerce platform that speaks regional languages and unifies online and offline commerce.

What it does

AURA is a multi-language, AI-powered e-commerce platform designed for both customers and small merchants.

Enables shopping in Tamil, Hindi, and English
Supports voice-based and text-based product discovery
Provides a unified POS system for online and in-store sales
Synchronizes inventory in real time to prevent overselling
Delivers fast checkout (2 minutes vs 12 minutes on traditional platforms)
Sends real-time order updates via Telegram notifications
Includes loyalty points, support tickets, and merchant dashboards

How we built it

AURA is built on the MERN stack (MongoDB, Express, React, Node.js) with a **multi-agent AI system powered by Google Gemini_.

Core Architecture

Frontend: React 18 with Redux and Bootstrap (responsive UI)
Backend: Node.js + Express REST APIs with JWT authentication
Database: MongoDB for flexible data storage
AI Engine: Google Gemini for multi-language understanding
Payments: Stripe (PCI-compliant)
Notifications: Telegram Bot API

Development Timeline

Week 1: Authentication, product catalog, responsive UI
Week 2: AI integration, multi-agent system, voice & barcode input
Week 3: Unified POS, merchant dashboard, admin panel
Week 4: Payments, notifications, loyalty system, security audits

Challenges we ran into

Multi-language context loss
When users switched between Tamil, Hindi, and English, the AI sometimes lost context.
Solution: Persistent context storage across language switches.
Inventory race conditions
Simultaneous online and in-store purchases caused overselling.
Solution: Optimistic locking and atomic database transactions.
Payment security vs user experience
Maintaining conversational checkout while ensuring PCI compliance.
Solution: Stripe secure elements — card data never touches our servers.
Barcode scanning accuracy
Poor lighting and low-quality cameras reduced accuracy.
Solution: Image preprocessing with manual fallback options.
Cross-browser compatibility
Voice and camera access behaved differently across devices.
Solution: Progressive enhancement with feature detection.
