• Used Spring for bean instantiation, annotations, controllers, request mapping to handle the Web service request and response.• Designed and implemented microservices using Quarkus, ensuring seamless integration and communication between different components of the welfare management system.• Developed REST Webservices to make web service calls simple and easy for the client to access it with the help of standard HTTP URIs.• Integrated Cassandra with Java-based backend services, ensuring fault-tolerant and distributed data management.• Managed Unix/Linux environments for deploying and maintaining Java-based applications, ensuring system stability and performance.• Implemented end-to-end automated tests to ensure the integrity of critical workflows, such as case management and financial transactions.• Developed an inventory management system using Python and Django.

Java, Eclipse, Spring MVC, Linux, Agile Methodology, SQL, JSP, Apache Tomcat, HTML, GIT, Maven, JavaScript, JDBC, XML, and Jboss Wild Fly.

•Involved in all phases of the Software development life cycle (SDLC) using Agile Methodology in writing Spring MVC Configuration XML file that contains declarations and another dependent object declaration. •Developed user interface using JSP Tag libraries, third party libraries and Java Script to simplify the complexities of the application•Inserted Dependency Injection between components using Spring (IOC) concept implemented Asynchronous messaging between components using JMS.•Used Spring Security to provide authentication, authorization and access-control features for this application wrote Stored Procedures and complicated queries for IBM DB2 •Implemented SOA architecture with Webservices using SOAP, WSDL, UDDI and XML using Apache CXF framework tool/Apache Commons worked on parsing the XML files using DOM/SAX parsers•Designed and developed Hibernate DAO's using Spring Framework's Hibernate Dao Support and Hibernate Template. • Optimized data storage and retrieval processes using Cassandra, improving system performance and scalability.•Monitored and optimized system performance, analyzing log files, and handling debugging tasks using Unix/Linux commands and tools.•Involved in coding used Struts, Spring and Hibernate, REST/SOAP Webservices, JSF frame works in the development of the User Interfaces using HTML, JSP, JS, CSS and AJAX. •Involved in creating various Data Access Objects (DAO) for addition, modification and deletion of records using various specification files created JAX-RS REST API for GET, POST, PUT and DELETE requests•Implemented Log4J for Logging Errors, debugging and tracking using logger's components performed deployment of applications on IBM Web Sphere Application Server.

• Involved in various phases of Software Development Life Cycle (SDLC) such as requirements gathering, modeling, analysis, design, development and testing.• Developed various helper classes needed following Core Java multi-threaded programming and Collection classes.• Developed the User Interface using JSP, Spring MVC frameworks, JQuery, React JS. Used AJAX, React JS and JavaScript for Server side/client-side validation.• Used Spring framework AOP features and JDBC module features to persist the data to the database for few applications. Also used the Spring IOC feature to get hibernate session factory and resolve other bean dependencies.• Created RESTful web services interface to Java-based runtime engine and accounts.• Used JAX-WS and Metro stack for building of Web Services. Also developed the web service client applications to test the web services. Tested the web service using SOAP UI.• Actively used the defect tracking tool JIRA to create and track the defects.
