Overview

At Springer Nature, I led the integration of multiple microservices with Razorpay to build a robust, scalable payment processing system.

Problem

The existing payment flow lacked a unified gateway integration, leading to inconsistent payment experiences and manual reconciliation overhead.

Solution

Built a microservices-based payment layer that integrated with Razorpay's APIs, handling payment initiation, webhook callbacks, retry logic, and reconciliation — all with comprehensive test coverage using TDD.

Tech Stack

• Kotlin / Java — Backend services
• Spring Boot — Framework
• Microservices — Service architecture
• Razorpay — Payment gateway
• TDD — Test-driven development approach

My Role

• Designed the payment integration architecture
• Implemented Razorpay webhook handling and retry mechanisms
• Spearheaded adoption of Kotlin and TDD for the backend
• Mentored junior engineers on the team

Impact

Delivered a seamless payment experience for end-users at scale, with reliable transaction processing and automated reconciliation.
