Case Study

Shared Payment Gateway

A centralized backend payment gateway service that powers all client event/hype websites. Acts as a common integration layer supporting Razorpay, PhonePe, and other providers, successfully decoupling payment logic from individual frontends.

Python/Django REST API Multi-Provider

error_outline The Problem

Fragmented payment integrations across 40+ client sites created maintenance nightmares and security vulnerabilities. Each frontend required bespoke integration logic for various payment providers, leading to duplicated effort and unreliable transaction tracking. A centralized, secure backend architecture was essential to standardise the payment flow.
