A professional specializing in Full Stack development with Spring Boot and React is skilled in using both of these powerful technologies to build robust, scalable web applications. Spring Boot is a Java-based framework used for creating enterprise-level back-end applications, while React is a JavaScript library developed by Facebook for building interactive and dynamic user interfaces. Combining these two technologies allows developers to create full-fledged applications with efficient back-ends and responsive front-ends.
