➢Worked in the AGILE development environment to design and implement multi-tier applications using web-based technologies like Spring MVC and Spring Boot. ➢Used various Core Java concepts such as Multi-Threading, Exception Handling, Collection APIs to ➢implement various features and enhancements. ➢Created a set of classes using DAO patterns to decouple the business logic and data. ➢Implemented Hibernate in the data access object layer to access and update information in the SQL Server Database. ➢Exposure to the Angular application that directly communicates with the service we developed and designed. ➢Used Oracle as a database and implemented Spring Data JPA. ➢Implemented Kafka to handle the real-time feeds. ➢Used Spring Dependency injection to inject all the required dependencies in the application. ➢Developed screens, Controller classes, business services, and Dao layer respective to the modules. ➢Involved in developing the Business Logic using POJOs. ➢Designed, developed, and maintained the data layer using Hibernate and performed configuration of EJB. ➢Used Maven for building the application in a local machine and then did a code walkthrough to analyze the issue which is lowering the performance of the application. ➢Exposure to Spring reactive application. ➢Implemented Java Stream API as well as implemented multithreading in an application using java concurrency library. ➢Developed RESTful APIs for employee management applications using Java Spring-Boot API and new feature additions in the current Microservices. ➢Built both synchronous and asynchronous services using Rest APIs. ➢Deployed application in Netty application server and used Maven as build tool.

➢ Designed brand-new Dynamic GUI using Spring MVC framework, Angular, Spring Hibernate, SpringSecurity, HTML5, and CSS3➢ Built dashboard by using Angular Components, Directives, Pipes, Form, Router to realize functionalities.➢ Developed application using Spring (Spring MVC, Spring Boot, Spring IOC, DI) and the persistent layer using JPA.➢ Using Java8 concepts like lambda expressions and streams while loop iterations and functional interfaces with default method implementations.➢ Used Spring REST Web Service and Hibernate which provides loose coupling between user interface layer and persistence layer.➢ Used JPA with Entity Beans for interacting with Persistence Layer for CRUD operations.➢ Used Hibernate for mapping Java classes with database using Hibernate Query Language (HQL).➢ Rest architecture-based web services to facilitate communication between client and servers and used Postman to test the web service responses.➢ Produced and consumed centralized Spring Restful Web Services for Enterprise and web applications to consume in JSON format and trusted client-server environment.➢ Experience in creating request-response POJOs for JSON response through Data Transfer Object Layer.➢ Unix shell scripts for logs and cron jobs.➢ Worked on build/deploy tools such as Jenkins, Docker for Continuous Integration & Deployment forMicroservices.➢ Hands-on experience in writing unit test cases using Junit and Mockito framework.➢ Hands-on experience in visual exploration and real-time analysis of data and application logs using Elastic Search tool Kibana.➢ Worked on Git as version control management and JIRA as Defect management for the bug, issue tracking of application. Used Jenkins for CI/CD process.Environment: Spring Boot, Spring MVC, Angular, Spring Hibernate, Spring Security, HTML5, CSS3, Spring IOC, DI, REST Web Services, JPA, HQL, Jenkins, Docker, Mockito, Elastic Kibana, Jira, GIT
