As a Java Developer, I played a key role in the full software development life cycle, from requirement gathering, analysis, and design to implementation and deployment. I developed user interfaces using HTML, JavaScript, AJAX, and JSP to deliver responsive, dynamic web pages. My expertise in the Spring and Hibernate frameworks was crucial in building scalable applications, using Spring MVC to define Dispatcher Servlet, Controllers, and View Resolvers, and leveraging Hibernate to map business objects to Oracle DB via XML configuration.In this role, I focused on optimizing performance by configuring JBoss Application Server, handling workload management, and tuning application performance. I also implemented DAO objects with Hibernate, utilizing HQL (Hibernate Query Language) for effective database querying. Additionally, I worked with PHP and MyAdmin portal for database configuration and services, while implementing JavaScript for data validation and interaction across multiple web pages.I also utilized technologies like EJB session beans for mobile session management, validating user sessions, and maintaining credentials. I worked with JPA frameworks, including JDO and Hibernate, for persistence and serialized data management using JSON. Moreover, I created shell and Perl scripts to connect with databases and retrieve data from multiple sources, further ensuring efficiency and system automation. My tech stack included J2EE, JSP, Servlets, JDBC, JAXB, Apache Tomcat, Oracle, MySQL, and other open-source tools like Log4j, validation files, and resource bundles.
