 Involved in various phases of Software Development Life Cycle (SDLC) of the application like Requirement gathering, Design Analysis, and Code development. Used Agile practices and Test- Driven Development (TDD) techniques to provide reliable, working software early and often. Worked with core java concepts like Collections Framework, Multithreading and Memory management. Developed presentation layer using JSP, HTML5, CSS3 and client validation using JavaScript. Implemented Single Page Design and customized directive and filter criteria by using AngularJS, which can allow data binding to specific views and synchronize the data with server. Used React JS for frontend framework and Redux architecture for creating data layers for unidirectional data flow. Built Web pages that are more user-interactive using HTML5, CSS preprocessors like LESS, JavaScript, React JS, React-Redux and Redux- Saga. Implemented ReactJS client-side form validation to validate the user inputs before passing to back-end. Performed Restful routing using Node.js which submits my form data to the Mongo DB database. Implemented Microservices using Pivotal Cloud foundry (PCF) platform build upon Spring Boot Services. Worked on development and implementation of the MVC Architectural pattern using Spring Framework. Developed the application with various Spring Framework modules like Spring MVC, Spring IOC, Spring AOP, SpringBoot and Spring Security.

 Involved in the complete SDLC (software development life cycle) of the application from requirement analysis to testing. Followed Agile Methodology in analyze, define, and document the application, which will support functional and business requirements. Coordinate these efforts with Functional Architects. Developed the application using J2EE Design Patterns like Business Delegate, Factory, Singleton, Session Facade, Service Locator and DAO.  Implementation of a responsive UI which will scale itself depending on the device, platform and browser, using AngularJS, Typescript, HTML5, CSS3, Bootstrap. Worked with both AngularJS and React JS for developing Dynamic Single Page Application. Worked on Angular 4 by consuming Restful web services & used Angular 4 forms like Template Driven forms and Modern Driven (Reactive) forms to perform form validations both on server and client side.  Designed and developed application using Spring Framework modules like Spring IOC, Spring AOP and handled security using Spring Security OAuth. Designed and developed Restful service interface using Spring MVC to the underlying customer event API. Involved in building Restful Web services using JAX-RS API. Developed Micro Service to provide RESTful API utilizing Spring Boot with Spring MVC. Developed REST and SOAP based Web Services for data retrieval to make it independent of the current application.

 Involved in all phases of SDLC like Design & Analysis of the Customer Specifications, Development and Customization of the Application. Analyzed the system for Requirements and Design by developing Use Case, Class, Sequence and Collaboration Diagrams using Visio as part of UML & created documents. Designed User Interfaces using JSP, JavaScript, HTML, CSS and jQuery.  Used Angular and Bootstrap to develop the user interface to validate the user at client side and provide responsive feedback. Ensuring the high performance of the application on mobile devices and desktop. As part of AngularJS development have used data-binding and developed controllers, directives, and filters and integrated with the backend-services. Developed the entire application implementing MVC Architecture integrating JSF with Hibernate and spring frameworks. Used Hibernate Detached Criteria, HQL and written some SQL queries for data retrieving. Implemented Spring configuration files for the beans defined and properties to be injected into them using Spring Dependency Injection. Used Singleton, Spring MVC, Hibernate, Factory Pattern and DAO design patterns.

 Analyzing System Requirements and preparing System Design document, Mockup documents. Full life cycle experience including requirements gathering, business analysis, high level design, detailed design, data design, coding, testing, and creation of functional documentation. Implemented Core Java coding and development using Multithreading and various design Patterns. Used agile methodology such as extreme programming to improve the quality of code and to meet the change in customer requirements even at the late stage of development process.  Worked on the web page enhancements using HTML, CSS, Angular, JavaScript, Servlets and JavaBeans. Used Hibernate framework in persistence layer for mapping an object-oriented domain model to a database.  Implemented Hibernate Caching for frequent queries executed against database for reports.  Implemented various design patterns in the project such as Business Delegate, Session Façade, Data Transfer Object, Data Access Object, Service Locator and Singleton.  Designed validation component using Struts common's validation framework to validate data, based on the requirement developed validation rules to accommodate special business rules Worked on Exposing and consuming SOAP based webservices to integrate application modules Involved in coding for the presentation layer using Apache Tiles Framework, AJAX, XML, XSLT and JavaScript. Used Rational Clear Case and Clear Quest for version control and change management.  Used ANT scripts to build the application and deployed on WebSphere Application Server.
