 Followed agile methodology for developing application and involved in analysis, design, and development and testing phases of Software Development Life Cycle(SDLC). Used Microservices to build individual components of the application and built the application on spring 4.x Framework. Used J2EE Design Patterns as Singleton, Facade, Proxy, and Observer for Middle Tier Development as well as Composite View Pattern for presentation tier. Implemented Spring MVC flow to interact with different modules of the application. Built and consumed RESTful services in modules and implemented serialization using Spring REST and JSON. Designed and developed the REST based Microservices using the Spring Boot, Spring Data JPA.

 Knowledge and experience working in an agile environment. Involved in a full lifecycle of the project from requirements gathering to development stage using Agile Methodology. Worked on developing and leading new modules, enhancements and change requests, post production release activities. Designed and developed java backend batch jobs to update the product offer details. Expertise in developing J2EE web applications using Java, Spring MVC framework, Spring Boot, Hibernate ORM framework and JPA, JSP, Servlets, Restful & SOAP Web services. Designed and developed web-based applications using HTML5, CSS3 and JavaScript and bootstrap framework. Involved in document analysis and technical feasibility discussions for implementing new functionalities. Applied design patterns including MVC Pattern, Façade Pattern, Abstract Factory Pattern, DAO Pattern and Singleton.

 Involved in all phases of the Software development life cycle (SDLC) using Agile Methodology, designed use case diagrams, class diagrams, and sequence diagrams as a part of design phase. Prepared Technical Design documents with UML diagrams using Microsoft Visio. Extensively used the core-concepts of java such as Stream API, Exception-handling and Collections for business logic development. Integrated JAVA EE technology Spring MVC with Hibernate for the persistence layer access for mapping to the tables in the Oracle 12c Database. Implemented Microservices architecture for the creation of the independent components utilizing Spring Boot for consuming full services. Developed Microservices with Spring Eureka to retrieve API routes for the entire cluster. Using this strategy each spring service in a cluster can be load balanced and exposed through one API gateway.

 Defined and constructed layers, server-side objects and client-side interfaces based on J2EE design patterns, Developed and implemented Swing, spring and J2EE based MVC (Model-View-Controller) framework for the application. Developed web applications using Spring MVC, jQuery, HTML5, Bootstrap and worked on Multithreading and Collections framework. Added interactivity to the UI pages using JavaScript. Struts Tag Libraries and Struts Tiles Framework were used in addition to JSP, HTML, AJAX and CSS in developing the presentation layer. Worked with Core Java technologies Collections, Serialization, Generics, Annotations and Exception Handling to implement Back-End business logic including Entity and Session Beans.
