Java/J2EE with ReactJS/AngularJS based Cloud application performing Stock Market Technical Analysis

We currently possess an in-house Java/J2EE application dedicated to performing technical analysis on the US Stock Market, utilizing the latest trading data. The application has been developed using J2EE technologies such as Spring JPA, Spring JDBC, REST Web Services, Java Streams, Lambda expressions, Spring Boot, Swagger API, and Microservices architecture. It currently exposes multiple REST-based Microservices. We are seeking significant enhancements for the application, including the development of a front-end interface using AngularJS or ReactJS to interact with the Java application based on Spring Boot. Additionally, we aim to augment the existing Spring Boot application by incorporating additional Stock Market APIs and leveraging cloud technologies like AWS, transforming the application into a technological showcase.
