PROFESSIONAL EXPERIENCE

Confidential, Piscataway, NJ

Java Developer

Responsibilities:

• Used Spring Boot which is radically faster in building Microservices and develop spring-based application with very less configuration.
• Developed controllers and services for handling the requests using Spring Boot
• Managed Declarative Transactions using Spring AOP and also integrated Spring with REST
• Utilized Java 8 features like Lambda expressions and Stream API for Bulk data operations on Collections which would increase the performance of the Application.
• Extensively used Hibernate in data access layer to access and update information in the database.
• Used Log4J for any logging purposes during the development of the application.

Environment: Java 8, Spring IOC, Spring AOP, Spring Boot, HTML5, CSS3, JavaScript, Angular 4, Hibernate, Oracle Db, Log4J, Maven, Jenkins, Eclipse, GitHub, JUNIT, Mock

Java Developer

Responsibilities:

• Implemented some applications by using Object Oriented Programming concepts, Multi-Threading, Exception Handling, and Collections while developing the project.
• Used Spring Boot framework for building Micro Services and to develop Spring based application radically faster with very less configuration.
• Developed the persistence layer using Hibernate Framework, created the POJO objects and mapped using Hibernate annotations and Transaction Management.
• Developed the application using J2EE Design Patterns like Business Delegate, Factory, Singleton, Session Facade, Service Locator and DAO.
• Involved in designing the database and coding of SQL, PL/SQL, Triggers and Views using MySQL.
• Worked on Log4J to validate functionalists and used JIRA to assign, track, report and audit the issues in the application.
• Used GIT 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.

Confidential, Santa Cruz, CA

Java Developer

Responsibilities:

• Implemented Multi-Threaded Environment and used most of the interfaces under the Collection framework by using Core Java concepts.
• Involved in developing code using major concepts of Spring Framework Dependency Injection (DI) and Inversion of control (IOC).
• Used Spring MVC framework for implementing RESTful webservices so that complexity of integration will be reduced, and maintenance will be very easy.
• Used advanced java 8 features like Lambda expressions for array operations, collections. Enhanced concurrency methods etc. throughout the application for well-defined programming.
• Used Hibernate to persistent the data into database and written HQL to access/update the database.
• Implementation of J2EE Design Patterns like Singleton, Session Facade, Business Delegate, and Data Access Objects.
• Written SQL queries PL/SQL Stored procedures, functions, triggers, cursors, sequences, and indexes, which are going to be invoked by Batch processes.
• Worked on setting up Maven scripts to build, package, and deploy application code to the target WebLogic Application Servers and worked on continuous integration servers like Jenkins.
• Focused on Test Driven Development there by creating detailed JUnit tests for every single piece of functionality before writing the functionality.
• Logging framework Log4J is used for log messages. Implemented log4j for application logging and to troubleshoot issues in debug mode.
• Used Jenkins for continuous build system and Git as version control.
