• Participate in the full life cycle of an agile project, design and develop user interfaces/applications, and conduct testing• Experience in implementing Web Services in-order to communicate between different distributed components using with SOAP Protocol using Apache Axis.• Designed and developed RESTful web services that support JSON for other developers to access, to speed up development using Spring MVC, Spring Boot, Web Services, JSON, Log4j, RESTful, MySQL and Maven.• Performed front-end and back-end coding through Linux OS CLI command.• Used Linux Shell Scripting to work within local and outside repositories. • Converted a monolithic app to microservices architecture using Spring Boot using 12-factor app methodology. Deployed, Scaled, Configured, wrote manifest file for various Microservices in PCF• Implemented REST Microservices using Spring boot. Generated Metrics with method level granularity and Persistence using Spring AOP and Spring Actuator• Worked on developing large scale, fault tolerance systems with Kafka, Storm, NoSQL databases (Cassandra & MongoDB).• Implementing streaming solutions and stream processing with Apache Kafka• Used Kafka for message handling and streaming the real-time data • Developed core business service APIs and delivered high quality APIs deployed on the Kubernetes platform

• Involved in the Analysis, Design, and Implementation of software applications using Apache Kafka, Spring MVC, JPA, JSF, Java, J2EE, SQL, XML and XSLT, and Web services (SOAP, WSDL).• Used Eclipse-IDE 2019 tool to develop the application. • Implemented J2EE design patterns like Singleton and Session Façade. • Implemented batch jobs for regular data updates and messaging queues. • Developed Facade classes to encapsulate the business logic and hide the implementation details of the data access classes and EJBs.• Involved in the design of the user interfaces using Java Swing and Sun Studio.• Developed Hibernate persistence layer modules using EJB Java Persistence API(JPA) annotations and Entity Manager. • Developed Action Classes, and Action Form Classes, created JSPs using Struts tag libraries, and configured in Struts-config.xml, and Web.xml files.• Involved java multithreading to cascade multiple changes on multiple records in only one transaction and developed a batch process framework.• Developed several Java Swing custom components to address the core business.• Developed User Interface having animations and effects using JSF, JavaScript, HTML, Angular 11 . • Build customer-friendly UI and back-end services for payment processing administration and management using Node.js.

• Worked on the development and testing of the infotainment module using Agile (SCRUM) methodologies.• Worked on requirement gathering and providing use cases for business, functional & technical requirements.• Mocking of services required for Unit tests in applications and setting up mock components for camel integration testing.• Responsible for designing the User Interface by coding in HTML5, CSS3, Bootstrap to build this SPA Single Page Application.• Developing Oracle Service Bus projects for integration between legacy systems.• Experience in developing proxy services, business services in Oracle Service Bus.• System was developed using Java/J2EE technology working closely with the core team and a scrum master.• Responsible for developing java components using Spring, Spring JDBC, Spring Transaction Management.• Used Spring JDBC in persistence layer that is capable of handling high volume transactions.• Used Spring framework for middle tier and Spring-JDBC templates for data access.• Used JavaScript for performing client-side validations.• Used Spring Framework in conjunction with Hibernate to develop backend functionality.• Implement modules into Node.JS to integrate with designs and requirements.• Experience in cloud native architecture of microservice using Jenkins and Docker.• Used Spring core annotations for Dependency Injection Spring DI and Spring MVC for REST API's and Spring Boot for micro-services.• Used Spring framework to achieve loose coupling between the layers thus moving towards Service Oriented Architecture (SOA) exposed through Restful Services.• Designed and developed various modules of the application with Spring MVC architecture and Spring Bean Factory using IOC, AOP concepts.• Participated in requirement gathering and framework implementation sessions through Agile TDD methodology.
