Experience with REST-based Maven applications. Microservices are on the rise. ● Experience with Hibernate and JPA, as well as writing custom queries for complex operations. ● Assisting with bi-weekly releases and acting as a scrum master for the development of Angular, Spring Boot, and Struts applications. deployment monitoring for DEV, TEST, and PROD environments. ● I worked on the mobile application's front-end java script implementation. ● Spring Boot was used to design and develop RESTful Microservices for the application's seamless integration with supporting subsystems. ● Pushed and pulled code to and from repositories, which I used for continuous codebase development across my teams. ● Views for the app were added and updated, and state management was implemented using Redux. ● In each sprint, I worked on Angular 9 and created UI controller components, Angular Services, and custom directives. ● Designed and processed JSON requests based on different types of modules actions request data and responses to send back to the front end after logic processing. ● HTML5, JavaScript, and CSS3 were used to design and implement the application. ● Responsible for writing java code to consume RESTful APIs. ● Python and Django were used to interact with the jQuery UI and manage content storage and deletion. ● JUnit test cases were created for testing various Java components, and the J-Test tool was used for performance testing. ● Used Postman to test the application's smooth workflow, how the application is changing with the newly developed functionalities, and the output for the web services. Environment: Java 8, HTML5,Spring Boot, Angular 9, SSRS, Power BI, SSAS, Agile Methodology, GitHub, GitLab Microservices, Oracle 11g, Java Script, React-Native, JUnit, Node.js

●Assisting with bi-weekly releases and acting as a scrum master for the development of Angular, Spring Boot, and Struts applications. Bamboo deployment monitoring for DEV, TEST, and PROD environments. ●Developed various modules using Java, Apache Camel, Spring Boot, and camel routing to integrate web services. ●Based on the requirements, I used Kafka to produce and consume topics. I'm currently using Junit for unit testing and Postman API for end-to-end testing. I built the application with Spring Boot and handled security with Spring Security. ●Used JIRA platform to create, manage, monitor, and complete stories while working on Agile software development methodology, attending daily SCRUM meetings . Azure Deployment Engine is also used for deploying and testing the lower environments such as DEV, TEST, and PROD. ●DAO layer was implemented using Spring JDBC Module to call DB2 stored procedures from the application. ●In the backend, Mongo DB was used to persist data into the database, and SQL/Mongo queries were witten to access/update the data from/to the database. ●Spring Web services JAX-RS JSON Spring MVC Module is used to develop and support Restful Web services that support JSON. ●HTML5, JavaScript, and CSS3 were used to design and implement the application. ●I worked on the mobile application's front-end React Native implementation. ●In each sprint, I worked on Angular 9 and created UI controller components, Angular Services, and custom directives. ●Responsible for writing Python code to consume RESTful APIs via Flask. ●Python and Django were used to interact with the jQuery UI and manage content storage and deletion. ●Spring Kafka API calls were used to process messages on the Kafka Cluster setup. ●JUnit test cases were created for testing various Java components, and the J-Test tool was used for performance testing. ●For real-time performance, the DAO layer was built with Java Hibernate and a caching system.

●Participated in the analysis of client requirements, design, development, and testing of the application, as well as the creation of technical design and test case documentation. ●For form validations, HTML5, React JS, JSON, AJAX, and DOM scripting were extensively used. ●Designed and built a custom, single-page (SPA), responsive web application on the front end with React JS. ●In React JS, I implemented routing logic, screen navigation, and login functionality on the client side. ●Worked with JavaScript libraries and frameworks like Ext JS, React JS, and Object-oriented programming in JS. ●Using React JS components, such as Forms, Events, Keys, and Router, as well as Redux, Animations, and Flux concepts. ●Used Spring IOC, Spring MVC Framework, Spring AOP, Spring Boot, Spring Batch, and Spring Security to implement the application. ●Created the controller and DAO layer with Hibernate/JDBC templates and Spring IOC (Dependency Injection). ●Experience working with Java 8 Streams, functional interfaces, and Lambda Expressions. ●WebSphere resources, such as JDBC providers, JDBC data sources, and Java Mail sessions, have been configured. ●To implement the middle tier, Spring IOC, AOP, and Spring Boot were used. Microservices were implemented using Spring Boot. ● Creating REST API implementations with the Spring Boot framework and writing API test cases. ●Created REST-based Web Services using XML/JSON messages for the front end. ●Developed Web-Services to integrate various applications (internal and third-party components) using RESTful services and Jersey. ●Used Postman to test the application's smooth workflow, how the application is changing with the newly developed functionalities, and the output for the web services. ● Used Spring data MongoDB to perform database interactions such as creating, updating, deleting, and reading MongoDB documents. Using spring data MongoDB, I created Mongo DB embedded documents from java code.

● Implemented a Continuous Integration/Deployment (CI/CD) pipeline to simplify the development process; reduced deployment time by 70% and increased production deployment frequency by 2X. ● Implementation of a responsive UI that scales based on device, platform, and browser using Vue JS, HTML5, CSS3, Bootstrap, and JavaScript client-side validations. ● Strong experience developing Web Services with SOA, SOAP, WSDL, and XML. ● Experience with tools such as POSTMAN. And create methods such as MAVEN. ● Using the Gradle Script build framework, automate the build process. ● Cloud architecture based on microservices on Amazon Web Services (AWS) Platform and Cloud Foundry. ● Authorized SOA architecture with SOAP and XML web services using Apache Commons. DOM/SAX parsers were used to parse the XML files. ● Implemented the GitHub version control system to maintain and merge the code base; shortened the development process and reduced code conflicts, saving 10+ hours per week. ● Developed a comprehensive testing suite for a complex financial application with 200+ screens using JUnit and Mocha/Chai; reduced testing time by 50%, ensuring timely product release. ● JUnit and Mocha/Chai were used to automate 500+ test cases, resulting in a 60% reduction in regression testing time and a 90% reduction in human errors, resulting in a 30% increase in release frequency.
