The Challenge

Fleet Mart needed a B2B e-commerce platform with strict order approval workflows to prevent fraudulent purchases — a significant problem with their previous system.

My Role

Backend developer responsible for:

Laravel REST API architecture
JWT authentication system
Multi-tier approval workflow engine
Razorpay payment gateway integration

Technical Highlights

Multi-Tier Approval Workflow

Designed a state-machine-based approval system:

  Order Created → Manager Review → Finance Approval → Payment → Fulfilled
       │              │                  │
       ▼              ▼                  ▼
    Cancelled      Rejected           Rejected

Each tier has role-based access, email notifications, and audit logging.

Fraud Prevention

The multi-tier approval system, combined with JWT authentication and audit trails, reduced fraudulent orders by 90%.

Payment Integration

Razorpay API for Indian payment methods (UPI, cards, netbanking)
Webhook signature verification for payment confirmations
Idempotent processing to prevent double charges

Key Results

Served 500+ users on the platform
Reduced fraud by 90% through multi-tier approvals
Reliable payment processing via Razorpay
Full audit trail for compliance
