   Spearheaded the development of secure RESTful APIs using Java 11, 17 and Spring Boot for core banking modules such as transaction history, fund transfers, and account alerts, resulting in improved stability, faster response time, and better customer experience across mobile and web platforms. Designed and enforced token-based authentication using JWT, OAuth2, and Spring Security, replacing outdated session-based models. This reduced unauthorized access incidents by 42%, enhanced traceability, and strengthened compliance with audit and data protection policies. Revamped and refactored legacy DAO layers using JPA and Hibernate, addressing bottlenecks like N+1 queries and excessive eager loading. The improvements reduced database latency by 35%, especially during fund transfer volumes and reconciliation windows. Integrated RabbitMQ for asynchronous communication in the credit evaluation pipeline, enabling reliable event-driven workflows. This resulted in a 60% drop in timeout failures, increased throughput by transactions/hour, and enhanced SLA adherence. Worked closely with frontend engineers (React.js teams) to debug and resolve CORS issues, token expiry mismatches, and RBAC misconfigurations across environments. These efforts led to a 23% reduction in support tickets tied to integration bugs. Developed comprehensive API test collections in Postman, incorporating pre-request scripts, variables, and environment-specific test setups. Automated testing of 50+ REST endpoints across UAT and staging environments cut QA hours by 40% per sprint.
