Overview

Aura eCart is a multi-vendor e-commerce and referral-based marketplace platform built as a freelance project. The system allows users to purchase products, earn referral rewards, manage wallet balances, and redeem credits for discounts or withdrawals after verification.

The platform evolved from a standard e-commerce system into a hybrid model combining shopping, referral incentives, wallet management, and manual KYC-based financial operations.

Key Features

Multi-Vendor Marketplace - Multiple sellers can list and manage their own products within a shared platform.
Product Catalogue & Orders - Category-based product browsing with cart, checkout, and order tracking system.
Coupon & Discount System - Flexible coupon engine supporting percentage and fixed discounts.
Referral Reward System - Users earn coins when referred users complete purchases.
Wallet System - Internal wallet allowing users to store, accumulate, and redeem earned coins.
Coin Redemption - Users can convert earned rewards into discounts or withdrawal requests.
KYC Verification Module - Manual verification flow for identity documents (Aadhaar, PAN) before enabling withdrawals.
Payout Management System - Admin-side workflow for approving and processing withdrawal requests.
Support Ticket System - Built-in ticketing system for user queries and issue resolution.
Marketing / Reseller Portal - Separate connected portal for referral tracking, earnings, and reseller management.

System Architecture

The platform was built using a dual-portal architecture:

Main E-commerce System
- Product listings
- Orders
- Vendor management
Marketing / Reseller Portal
- Referral tracking system
- Wallet and coin management
- KYC submission and approval
- Withdrawal requests

Both systems were kept in sync using secure HTTPS-based integration between portals.

Key Engineering Highlights

Referral Economy System

Implemented a non-trivial reward system where users earn coins instead of direct cash rewards. These coins can later be used for discounts or withdrawal requests after approval.

Wallet & Financial Flow

Built a wallet system supporting:

Coin accumulation
Redemption logic
Withdrawal requests
Manual admin approval flow

This required strict consistency handling to prevent misuse or duplicate payouts.

KYC Verification Workflow

Users submit identity documents which are reviewed manually by backend staff before enabling financial actions like withdrawals.

Multi-System Integration

A separate marketing portal was introduced later and integrated with the main system over secure HTTPS communication to keep:

referral data
wallet balances
user rewards

fully synchronized across both systems.

Operational Modules

Ticketing system for customer support
Admin-controlled payout processing
Vendor management system for multi-seller operations

Challenges

The biggest challenge was evolving a standard e-commerce system into a referral-driven financial ecosystem without breaking existing order flows.

Maintaining consistency between:

wallet balances
referral rewards
order payments
withdrawal requests

required careful state management and strict validation rules across both portals.

Outcome

The platform successfully supported:

Multi-vendor e-commerce operations
Referral-based growth system
Wallet-based reward economy
Manual financial verification and payouts

It became a complete hybrid system combining e-commerce, affiliate marketing, and internal financial workflows.
