At Image InfoSystems, I work across two enterprise products: 🏦 Cheque Truncation System \(CTS\) — a core NPCI\-integrated banking platform handling real\-time interbank cheque processing across multiple banks\. My work here covers backend module engineering with Java, Spring Boot, and Hibernate; NPCI file pipeline optimization; SOAP/REST API design for real\-time interbank operations; and cloud deployments on AWS \(ECS, Lambda, RDS\) via Tomcat, JBoss, and WebLogic\. 🧾 VAT Engine — an enterprise tax compliance platform serving banks, businesses, and government compliance bodies\. I build multi\-jurisdiction VAT/GST tax rule modules, configurable rate engines, and full\-stack features using Java, Spring Boot, and ZK Framework — contributing to a 60%\+ increase in transaction throughput through backend optimization\. On the technical side, I work extensively with Java concurrency \(ExecutorService, CompletableFuture, thread pools\) to parallelize batch jobs, and I've led a Java 8 → Java 21 migration on a live banking codebase\. I also introduced structured observability via SLF4J/Logback and Spring Boot Actuator\. Beyond my core job, I build ambitious side projects\. Queueless is a full\-stack queue management platform I architected from scratch — Spring Boot 3\.2, PostgreSQL, Redis, Bucket4j for distributed rate limiting, JWT auth with RBAC, Razorpay payments, WebSockets for real\-time updates, and a React \+ React Native frontend\.
