•Involved in SDLC phases, including analysis, design, implementation, and testing, utilizing Java 8 features like Lambda expressions for code development.•Developed the Informant service layer and front-end using Spring MVC, configuring beans as per requirements and building cloud microservices with Spring Boot, deployed in AWS and Docker.•Created RESTful services in Spring Boot for JSON data retrieval, using Hibernate as the ORM tool to access SQL Server data.•Implemented JSON web tokens for authentication/authorization with Node.js, used JMS for asynchronous communication, and worked with XML for data exchange and schema validation.•Designed and managed AWS EC2 setup and configuration of resources like S3, Lambda, ECS, and VPC across different environments.•Developed EJB Stateless sessions for inter-layer communication, deployed on WebSphere Application Server, utilized JUnit and Log4j for testing and logging, implemented SOAP-based web services, and wrote complex SQL queries and stored procedures.

•Involved in analysis, specification, design, implementation, and testing phases of the Software Development Life Cycle (SDLC).•Used Java 8 features, including Lambda expressions, to create resource classes and fetch documents from the database.•Developed an Informant service layer using Spring MVC, configuring and wiring beans as per requirements.•Utilized Spring Boot for building cloud microservices with minimal configuration and deployed these services into containers using AWS and Docker.•Created Spring Boot RESTful services to retrieve historical data in JSON format from the database.•Developed POJO objects and employed Hibernate as the ORM tool for accessing persistent data from SQL Server.•Designed and implemented AWS EC2 Server setup, maintenance, and configuration, including resources like S3, Lambda, ECS, EBS, Elastic Load Balancers, VPC, and IAM Security Groups.•Implemented JMS for asynchronous communication.•Used WSDL and SOAP protocol for web services implementation.•Deployed the application on WebSphere Application Server, utilizing JUnit for unit testing and Log4j for capturing logs, including runtime exceptions.

•Worked with JSON web tokens for authentication and authorization security configurations using Node.js.•Worked on XML for data exchange, schema validation (XSD), and used XSLT for XML transformation.•Wrote EJB Stateless sessions to communicate with the Controller and Service layer, making EJB calls from Backing Beans.•Actively participated in weekly iterative review meetings, providing constructive feedback to track project progress and address issues.•Designed the database, created tables, and wrote complex SQL queries and stored procedures as per requirements.
