• Created the user interface in a responsive grid layout with HTML, XHTML, CSS/CSS3, jQuery, JavaScript, AJAX, JSP, JSF, and Angular 8. Responsive design template was used to create a new HTML5 and Bootstrap interface.• Developed Servlets/JSPs, JavaScript, jQuery, CSS, HTML, and DHTML were used to develop the view-controller components.• Worked with JAVA 8 features like Stream API, Functional Interfaces, Collection API.• Worked extensively on Core Java, particularly Multithreading, Exceptional handling, and Collections. • Executed database and web service testing using SQL queries. Using the JPA framework, made objects persistent.• Implemented RESTful Web Services to retrieve data from client side using Microservices.• Used the Spring Framework to design and create the backend for Restful services. Hibernate and SpringMVC was used in the development of middle-tier and business layer services.• Utilized J2EE design patterns such as the Value Object Pattern, Business Delegate, service locator, session façade, Singleton, Factory, and DAO.• Worked on Angular 8 component-based development has improved application performance in light of upcoming Angular framework changes. Developed a data ingestion application to use Apache Kafka and Spark Streaming to transfer data from a source system to HBase. • Worked on Java script automation of Angular JS applications using Protractor, Jasmine, and Karma• Utilizing Maven build scripts to automate the build and deployment process, the application was configured and deployed onto the Web Logic application server using Eclipse as the ID.

• Involved in analysis, specification, design, and implementation and testing phases of Software Development Life Cycle (SDLC) and used agile methodology (SCRUM) for developing application.• Developed competence in the implementation of core Java and J2EE technologies, including JSP, Servlets, JSF, JSTL, and EJB. • Used a middle-tier application using J2EE (SOAP, WSDL, UDDI) was developed using developed Servlets, EJB, Java Beans, and Web Services Standards.• To address a serious problem with the current application code, test techniques and unit testing were developed. Along with Mockito and Junit.• Developed Spring Boot application with Microservices and deployed it into AWS using EC2 instances.• Implemented asynchronous messaging service using Kafka in Microservices-based application• The J2EE design patterns like Factory, Singleton, Data Access Objects, and Data Transfer Objects, which make it simpler to distribute roles and responsibilities among various processing layers, were heavily used in the creation of the project.• Used spring framework to achieve loose coupling between the layers thus moving towards Service Oriented Architecture (SOA) exposed through Restful Services.• Used Apache Maven to build the application. Implementing the Microservices using Java/J2EE.• Created web pages for several small-scale startups using HTML, CSS, word press, JavaScript and Bootstrap.• The data access layer DAOs were constructed using experience with Hibernate ORM, which also produced configuration files and Hibernate mapping.• Created Connections using Spring JDBC to the database (Oracle11g) and developed SQL queries to manipulate data• Used IntelliJ as IDE for the application development and integration of the frameworks. Worked using WebLogic Application Server and the Eclipse IDE.• Used Log4j for external configuration files for debugging.• Good Knowledge and experience in using Elasticsearch, Kibana and fluent, Cloud watch and Splunk.
