I am responsible for evaluating requirements, planning, and creating efficient solutions using technologies like Java, Spring Boot, Angular, Hibernate, etc. for an enterprise online application for patent analysis. built REST APIs and utilized them to create Microservices.

Responsibilities:

• Applications are designed using J2EE, JSP, Servlets, Struts, WSDL, Web Services, JMS and used Spring Framework for Dependency Injection and spring bean wiring.
• Used Java 8 features such as streams, lambda expressions, functional interfaces, collections, and date/Time updates.
• Designed and implemented application using Spring Boot, Spring MVC, Spring IOC, Spring Annotations, Spring AOP, Spring Transactions and Spring JDBC.
• Used annotations in the complete project development, web services, MVC design. Used JMS for consuming pin verification, device connect disconnect messages.
• Used JPA as data persistence API for all the DAO, database operations. Used Mavenproject management tool for build and deployment of the application.
• Developed dynamic web pages using HTML/HTML5, CSS/CSS3, Bootstrap, jQuery, and AngularJS for enhanced user experience.
• Developed application using Java Spring MVC, JSP, JSTL and AJAX on the presentation layer, the business layer is built using spring and the persistent layer uses Hibernate.
• Involved in development of the web pages using AngularJS, JSP and Java Script and followed MVCmodel and used spring frameworks for developing the Web layer of the application.
• Created computing and data resources on AWS using EC2. Installed Pivotal Cloud Foundry on EC2 to manage the containers created by PCF.
• Used ReactJS to create views to hook up models to the DOM and synchronize data with server as a Single Page Application (SPA).
• Involved in creating and Deployment of REST APIand Microservices in Java /J2EE using Spring Boot.
• Built Java applications using Maven and deployed JAVA/J2EE applications through Tomcat Application servers.
• Applied design patterns including MVC Pattern, Facade Pattern, Abstract Factory Pattern, DAO Pattern and Singleton.
• Implement the technical transformation for the front-end from Angular JS to Angular 8 and built single-page applications using Angular 8 Routers.
• Implemented log4j for debugging. Utilized the same for logging each sensible data access from the application. Wrote unit and integration tests with Mockitoframework and used log4j for logging.
• Used GIT for Source Control and Version Management of all codes and resources.
• Used Agile methodologies during the complete project life cycle.
