• Developed a communication framework using the OKHttp2 and OKHttp3 clients to streamline communication between services by 80% - 85%, ensuring developers do not need to utilize numerous web client libraries.• Developed UI Builder APIs in Java to construct descriptions, which are then utilized by frontend code to generate React-based UIs for each Microservice. This approach empowers Java developers to create React-based UIs solely through Java coding. • Worked with Jmeter to perform the load Testing of this communication framework with more than 10 millionrequests. • Worked with different types of API – SOAP & REST. • Prepared a project focused on developing a Descriptive UI to support full-stack development of a Microservice, using technologies such as React.js, jQuery, and JsonEditor for the frontend, while Java is used for the backend.• Worked with OSGI and Spring-Boot framework• Managed Kubernetes and operations on our cloud-native platform for the team.
