The Problem
A marketplace needed to support multiple payment gateways (Stripe, Razorpay, PayPal) with automatic failover, split payments, refund management, and compliance across 12 countries.
The Solution
Designed an abstraction layer over multiple payment providers with strategy pattern, webhook reconciliation, idempotent retries, and a centralized ledger for financial reporting.
The Outcome
Processed $2M+ in transactions monthly with 99.97% success rate. Automatic failover reduced failed payments by 60%. PCI DSS compliant.
