Implement Core Java concepts like Multithreading, Collections, I/O, Generics, Exception Handling for complex business requirements.Implement Java 8 features such as lambda expressions, filters, Parallel operations on collections for effective sorting mechanisms.Process and store data using Java 8 features like Streams & Lambda expressions and design Singleton, Data Access Objects, Factory and MVC design patterns.Implement and enhance java based multithreading ETL tool for distributed loading XML data into MySQL database using JPA/Hibernate.Develop microservices application using Spring Boot and test the application with Spring Boot.Use Spring MVC for developing Restful APIs (web services), Spring Boot for microservices & Spring Core annotations for Spring Dependency Injection.Implement POJO’s & DAO’s for the database entities using Spring JDBC annotation mappings.Utilize microservices and decoupled architectures for building RESTful APIs. Implement Java Messaging Services (JMS) Pattern using Kafka for the reliable and asynchronous exchange of messages.Design complex SQL Queries, stored procedures & triggers on MySQL database.Deploy the application on Amazon Web services (AWS).Use Amazon CloudWatch to monitor AWS resources & Amazon CloudWatch Logs to collect and store logs from AWS services.Setup CI/CD pipeline process for the application using the Jenkins.

Involved in various phases of Software Development Life Cycle (SDLC) of the application like Requirement gathering, Design, Analysis and Code development. Used Reactive Forms Module with Angular 5 for easy custom validations. Developed reusable custom directives, components, pipes, and services. Involved in developing Angular 5 forms like Template Driven Forms and Reactive forms (Dynamic Forms) to perform form validation both on the server side and client side.Involved in using new features with Angular 5 like NgIf with Else, Pipes, compare selector and Validators followed by the client requirements.Refactored existing monolithic application by identifying components that needs to be transformed to Microservices architecture, with Spring Boot based service, interacting through a combination of REST and AWS API-Gateway. Used Spring Core Annotations for Dependency Injection Spring DI and Spring MVC for REST API s and Spring Boot for microservices.Developed SOAP as well as RESTful web services using CXF API and developed the services after the deployment on server using SOAP UI. Worked with Express.js for development of RESTful web services and middleware configurations. Involved in development of REST Web Services using Spring MVC to extract client related data from databases and SOAPUI tool is used for testing Restful API web services.Used JBoss6.x Application server to deploy the applications.Used Hibernate Query Language (HQL) for accessing data from database and created Hibernate POJO Objects and mapped using Hibernate Annotations.Implemented Hibernate annotations for the classes by replacing hibernate mapping xml files and Hibernate/JPA for data persistence.Involved in using JPA (Java Persistence API) frameworks and APIs such as JDO (Java Data Objects) and HibernateInvolved in writing application level code to interact with APIs, Web Services using AJAX, JSON and XML.

Used Structs framework MVC in the development of new modules based on requirements.Utilized various utilities like JSP, JSTL, JavaScript, HTML, & CSS, jQuery.Refactored existing project to make it more RESTful and thread safe.Involved in the creation of dynamic web pages with the use of JSP and HTML.Involve in the development of front-end screen design using JSP.Implement client side and server-side programming using HTML and JavaScript.Implement Core Java technologies like Multithreading, Collections and Exception Handling to solve complex business requirements.Debugged Java classes used to modify web pages such as Business Objects and Data Access Objects.Implemented JDBC to perform the database calls from the Java layer.Used JDBC to persist Java Objects into the database.Tested many components of web application and documented my observations. Participated in unit testing, integration testing and installation of the system.Contributed to the decision making of the software and hardware requirements and tool evaluations.Implemented logging for the whole application using Log4j.Involved in daily scrum meetings, worked on the sprint tasks in the Agile Scrum development.
