Razorpay Payment Gateway Clone

Developed a Razorpay-inspired payment gateway using Spring Boot and microservices, with dedicated services for merchant , payments, vault, and settlements. Implemented Kafka and the Outbox Pattern for reliable asynchronous communication and event-driven processing between microservices. Implemented webhook handling and API-key-based authentication for secure payment integration with merchants and external systems. Applied Redis-based cache rate limiting and Resilience4j patterns such as retry, circuit breaker, to improve reliability

ORMB Deep Links

ORMB is built as a single-page application. every screen, every drill-down, every context switch happens through internal JavaScript navigation. There are no shareable URLs, no way to duplicate a tab, and no way to open a bookmark without replacing what you already have open. If you've spent time in ORMB doing analysis, testing, or development, you've felt this. This post walks through how I extended ORMB's own deep link mechanism which documented for external integrations to solve these problem.
