 Utilized Agile methodologies and SCRUM meetings to optimize sequence diagrams and track progress. Implemented Advanced JDK 11+ features, including Lambda, filters, and predicates, and Stream API, to facilitate pipeline processing, as well as a method to eliminate elements based on a set of criteria. Implemented OAuth2 token-based authorization scheme using spring security to secure Rest API. Developed a Single Page Application (SPA) using Angular, SASS, Bootstrap. Data is bound to views and server-side synchronization is performed. Utilized Angular 8/7 framework to develop software in HTML, Typescript. Loaded modules lazily and maintain performance by creating nested lazy loaded modules. Created Angular Controllers for each view to keep data. Implemented Angular Service calls using Angular Factory. Implemented microservices with Spring Cloud and Netflix OSS components such as Eureka, Zuul, and Hystrix. Deployed Spring Boot microservices using Amazon EC2 container services. Deployed AWS-based RESTful services based on Micro Service Architecture from monolithic applications. Utilized Microservice architecture, with Spring Boot-based services that interacted via REST web services. Deployed and configured daily iterative builds of applications into Apache Tomcat servers using Maven.  Managed the integration of GitHub for the delivery of database scripts, source code, and other documents. Created and configured Jenkins CI servers to deploy Microservices and Lambda Functions. Enhancing and writing stored procedures and views. Utilized Oracle SQL queries to generate reports. Developed a HTTP request for sending JSON objects on the remote server and tested it with Advanced REST Client. Developed complex JIRA workflows, conditions, and set up and maintained JIRA.

 Developed applications using agile methodology, from requirements capture to testing and deployment. Worked on core Java concepts, such as OOP, Collections Framework, Exception Handling, I/O System, Multi-Threading, and JDBC. Develop Spring Controllers, Service Components, DAOs, Web Services, and UI integration. Developed and consumed RESTful Web Services for interaction between modules using JAX-RS and Jersey. Created, developed, and deployed a multitude of applications using the AWS stack (EC2, RDS, Elastic Beanstalk, S3, SNS, SES, and SQS). Improved the performance of backend batch processes using multithreading and concurrent package APIs. Utilized SOAP UI to validate SOAP and Restful web services. Utilized JAX-WS based Web Services for WSDL, UDDI, and SOAP communication. Added Oracle connection pool to MySQL JDBC driver JAR file to allow simultaneous database access. Build the application using Maven and deploy it on Apache Tomcat using the build tool. Captured runtime exceptions using Log4j. Debugged, integrated, and deployed the application using STS. Utilized JUnit as a framework for Test-Driven Development (TDD). Constructed server-side scripts to integrate GIT with JIRA and Jenkins.

 Developed reusable validation utilities that can be used across all modules such as OOPS, Multi-Threading, Collection APIs, and Memory Management. Developed WSDL documents, SOAP messages, and JAX-WS stubs for creating web services, using existing services, and generating stubs Provided regular status updates for Jira Tickets assigned and completed them on time Created, retrieved, updated, and deleted data in Oracle databases using complex SQL commands. Troubleshooting WebLogic and Oracle problems (killing instances, debugging server logs, applications logs) Implemented JAXB for request response and marshalling processes in the web service. Deployed Continuous Integration/Continuous Delivery (CI/CD) builds using Jenkins. Implemented new features using IntelliJ as the IDE and managed file versions using Git.
