Java/J2EE Developer

Responsibilities:

• Participated in vital phases of SDLC such as Designing, Developing and Maintaining of the application.
• Developed applications using Spring, Struts, J2EE and Java 8 features such as functional programming, lambda expression, stream, etc.
• Used various complex data structures in collections Framework in Java for writing the Business Logic.
• Developed Microservices architecture using Spring for making application independent and smaller.
• Developed data persistence mechanism using Spring JDBC.
• UsedSpringDAOconcept in order to interact with the database using JDBC template.
• UsedSpring SecurityManagement for user verifications.
• Customized RESTful Web Service using Spring RESTful API, sending JSON format data packets between front-end and middle-tier controller.
• Developed a Strong and secure administration for access control and restrictions at application and user level.
• Used DB2 as backend database and developed business logic using Core java and Spring MVC for processing the front-end request and to fetch the data from database.
• Developed UI pages using HTML, CSS, JavaScript, JSP and React JS that interact based on events.

• Used Node Js for executing JavaScript code.
• Configured and worked with Apache Tomcat Server, and used JUnit test cases to unit test the business logic.
• Developed scripts for maintaining ANT builds. Created and modified build configuration files.
• Developed Message Driven Beans (MDBs) for receiving and processing data from ActiveMQ using JMS and used multithreading for writing the collector parser and distributor process, which was getting Realtime data from API in format of JSON, using multithreading improved the performance by a lot. More over using concurrency package of collections made it thread safe.
• Used JMS (ActineMQ) for sending and receiving messages while using web services
• Used GitBash and Cygwin to maintain the version of the files and took the responsibility to do the code merges from branch to trunk and creating new branch when new feature implementation starts.
• Worked in areas of Jenkins setting up CI for new branches, build automation, plugin management and securing Jenkins and setting up master/slave configurations.
• Used QuickBuild and Jenkins to implementing the CI/CD during code releases.
• Created the branches in GitHub to implement the parallel development process.
• Configured and used Log4J for logging all the debugging and error information.

Environment: Core Java, Java/J2EE, Spring MVC, Spring Boot, Spring JDBC, Spring Security, RESTful web services, Struts, Junit, IBM WebSphere, Apache Tomcat, Ant, IBM DB2, Microsoft SQL, JMS, ActiveMQ, XML, HTML, CSS, JSP, JavaScript, React JS, QuickBuild, Jenkins, Version One, Cygwin, GitBash, GitHub, Visual Studio Code, Node JS, NPM, NVM, Log4J and Eclipse.
