Involved in all SDLC phases (requirements gathering to production deployment) in an Agile/Waterfall setting. Designed enterprise apps using Spring MVC/Spring Boot, implemented DAO patterns with Hibernate, and secured services with Spring Security, LDAP, and JWT. Built responsive UI with JSP/Servlets, and created reusable REST controllers with Spring Boot. Integrated Apache Kafka for real-time messaging and set up CI/CD pipelines with Jenkins and GitHub Actions. Led automated testing with JUnit, Mockito, and Cucumber and implemented logging/monitoring with ELK Stack and Prometheus/Grafana. Worked with DB2, Oracle, and PostgreSQL, and collaborated with mainframe teams for data synchronization. Supported UAT and production deployments.
