• Designed and coded application components in an Angular 8 environment utilizing a test-driven development and SDET approach and pair-programming.• Developed the application using spring framework that leverages model view layer architecture, also configured Dependency Injection.• Used Toad for Oracle DB to test out SQL queries in Dev and Test environment databases.• Writing unit tests in Angular front-end and making sure code coverage in unit tests was above threshold of 80% code coverage.• Fixing unit test cases for other parts of the front-end application in Angular on a regular basis.• Writing REST API calls in Java for the back-end application.• Following TDD for back-end application, making sure Junit test cases cover functionality properly. • Used Hibernate ORM tools which automate the mapping between SQL databases and objects in Java.

• Designed and coded application components in an Agile/TDD environment utilizing a test-driven development and SDET approach and pair-programming.• Developed the application using spring framework that leverages model view layer architecture, also configured Dependency Injection.• Used Hibernate ORM tools which automate the mapping between SQL databases and objects in Java.• Extensively used Hibernate in data access layer to access and update information in the database.• Design of GUI using Model View Architecture STRUTS Frame Work.• Integrated Spring DAO for data access using Hibernate. • Implemented unit test for testing Angular components with frameworks using KARMA and JASMINE• Created hibernate mapping files to map POJO to DB tables• Involved in the Development of Spring Framework Controllers• Developing application using spring core module and POJO's using Eclipse and worked on Messaging service.• Designed and developed the XSD for WSDL.

• Involved in developing Webservice operations in Service Oriented Architecture (SOA).• Analyze requirements with team; write High Level design documents, System Use Case, analyze risk factors.• Followed agile methodology during complete SDLC process.• Validated forms using Angular 2 and regular expressions there by providing client side validation and server validation• Participated Agile/Scrum development and deployment teams• Used Spring Framework 4.1 for the application development.• Created a custom analytics frame work to gather useful user behavior data using Mongo DB• Responsible for Web UI development in JavaScript using JQuery, AngularJS, and AJAX.• Involved in front end development using Struts, JSP's, JSF and JSTL.

• Implemented Different Design patterns like singleton, factory and J2EE design patterns like Business delegate, session facade, Value object and DAO design patterns.• Implemented AWS client API to interact with different services as Console configuration for AWS EC2.• Used Spring Framework’s IOC Dependency Injection to inject Service Object using Service Locator Design Pattern into Action Classes. • The application consisted of a monolithic codebase being slowly migrated to a microservices environment. Each microservices backend and frontend tech stack varied slightly from one another. • Implemented Unit testing using Junit. • Integration of spring modules with AWS modules in order to consume third party services.• Developed Webpages using UI frameworks bootstrap, Angular JS.• Created DHTML pages, used JavaScript for client-side validations and AJAX, AngularJS to create interactive front-end GUI.• Managed and maintained Oracle and NoSql databases in production domain. • Designed and implemented a NoSql based database and associated RESTful web service that persists high-volume user profile data for vertical teams

• Developed Code using Struts framework, based on the MVC design pattern• Developed the presentation layer using Struts Tag Libraries• Developed the application with iterative methodology, recapturing the existing code and writing a new code for most of the modules.• Utilized the AngularJS directives, factory, service and filters. Created number of custom directives to reuse them across the controller.• Created POC for Spring Batch for running batch jobs.• Worked on backend logic using Servlets, EJB, Hibernate and JDBC.• Developed page specific elements, handlers, web beans, view helper classes, JSP pages & fragments by using design patterns and java standards. Validating the Application by Deploying and testing on JBoss Server. • Developed micro services using Spring MVC, Spring Boot, Spring Cloud, Spring AOP and Dependency Injection and JPA. Used JDBC Connection, Statement to retrieve Data from RDBMS. • Analyzed, designed, validated the business logic of the system and implemented the application• Developed business services using EJB’s and used SOAP API.
