Involve in all phases of Software Development Life Cycle (SDLC) of the application like Requirement gathering, Design, Analysis, and Code development.  Develop web services (REST API) using Spring, Spring Boot, REST Architecture, used for storing and retrieving data using different URIs and HTTP methods.  Used MVC pattern to develop the Model, View, and Controller using Spring MVC, React and Restful service with Hibernate framework.  Worked on React.JS like text binding and writing classes using raw JavaScript and JSX files and developing user interface by using React JS, Redux, React Router for SPA development    Use Spring Data JPA and Hibernate with entity beans for interacting persistence layer for CRUD operations  Implement Stateless Security policies using spring security and JWT tokens with customized signatures. Used OAuth for authorization of the user to the application.  Involve in writing of multiple batch jobs using Spring Batch framework where both annotation & XML-based configuration is done to support various business functionalities.  Utilize Java 8 features like Lambda expressions and Stream API for Bulk data operations on Collections to increase the performance of the Application.  Implemented Spring JPA & ORM framework to interact with the database to perform all the crud operations based on business use cases.  For Dependency Injection, Spring Core Annotations were employed, and Apache Camel was used to integrate the Spring framework Create automated pipelines in AWS CodePipeline to deploy Docker containers in AWS ECS using services like CloudFormation, Code Build, Code Deploy, S3, and puppet.  Design, build and deploy an application for various environments using the AWS stack (Including EC2, MongoDB, Docker, Kubernetes Orchestration container (EKS) focusing on high-availability, fault tolerance, and auto-scaling and Load Balancing).  Worked on the development using Test Driven Development (TDD) approach.

Involved in requirement analysis, design, development, and testing phases of the Software Development Lifecycle (SDLC) leveraging Agile Methodology.  Used annotations from Spring, along with JPA and Spring Data JPA dependencies.  Designed and developed REST APIs using Spring Boot, as well as migrating from SOAP-based web services to RESTful services.  Designed stored procedures using Procedural Language for SQL (PL/SQL) for data manipulation, and design functions that utilize the stored procedures.  Performed code reviews and assisted team members in development or debugging.  Built interactive and responsive UI using JavaScript, React, and Bootstrap.  Developed and maintained a clean and user-friendly interface using React, jQuery, Ajax, etc.  Implemented J2EE standard MVC architecture using Spring Framework.  Involved in the development of services-based architecture utilizing technologies like Hibernate ORM with JPA Annotations and Spring MVC Framework.  Involved in implementing the JMS (Java messaging service) for asynchronous communication.  Used Eclipse with Tomcat application server for development and application deployment.  Worked in container-based technologies like Docker, Kubernetes, and Openshift.  Migrated the SOAP Web Services to Restful Web Services, designing the endpoints for sending and retrieving data.  Used MDBs (JMS) for asynchronous communication with the system.  Hands-on experience in testing, finding bugs, and resolving issues in the production server.  Supported QA in resolving issues by reproducing, diagnosing, and analyzing the root cause of bugs.  Developed unit test cases using Junit, integration tests using Jenkins, and used Log4j for logging.  Deployed WAR applications in the WebLogic Application Server Environment.

Implemented Spring Modules for Designing, Developing & Testing of Service Layer Business Components. Developed Message-based systems using Spring-JMS API and Message Driven POJOs. Involved in using JPA (Java Persistence API) frameworks and APIs as JDO (Java Data Objects) and hibernate. Used Spring Framework AOP Module to implement logging in the application to know the application status. Worked with configuring build tool Maven for the development and deployment. Developed Action classes, which communicate asynchronous messaging via JMS/MQ-Series to DB2. Implemented the application using Spring MVC Framework, Dependency Injection (IOC), AOP, Spring Batch. Used Hibernate ORM framework as persistence engine, configured hibernate.xml file, and Involved in Mapping, Coding, and Fine-tuning of Hibernate Queries. Implemented JUnit for application Unit Testing. Consumed Web Services (WSDL, SOAP, UDDI) from the third party for authorizing payments to/from customers based on SOA architecture. Developed front-end code with Ajax call-in and jQuery to retrieve data as JSON Object from controllers in back-end RESTful Server

Spring AOP was used for basic authentication at the API level, which cut down on development time for handling exceptions. Spring Boot and Spring DataJPA were used to implement the multi-tier applications. Spring Boot and Mongo DB were used to create a number of client-side web apps. Using JAX-RS and Spring Rest Controller, I developed a REST web service to expose some of the newly implemented functionalities to others. Spring MVC was configured, and Annotation was used to manage URL mapping with the controller for communication between levels.
