Very familiar with the properties of component, states, props, and refs.Hand on using React Hooks (State Hook, Effect Hook, Ref Hook and so on) to use state and lifecycle methods inside functional components.Called React Axios to get Web APIs to transfer data from backend and update the states in the store of Redux.Strong skills in applying Redux in React.js to store the status at the front-end.Implemented mapStateToProps, mapDispatchToProps, useSelector and useDispatch to interact between Redux and React.js.Converted a monolithic app to microservices architecture using Spring Boot. Deployed, Scaled, Implemented REST Microservices using spring boot. Generated Metrics with method level granularity and Persistence using Spring AOP and Spring Actuator.Developed workflows using RHPAMUsed Spring Beans to encapsulate business logic and Implemented MVC Architecture using Spring MVC framework.
