Course Overview
The Spring Framework fundamentally changed Java development. In this comprehensive course, you will transition from core Java concepts to building enterprise-grade applications. We focus heavily on modern practices, dedicating significant time to Spring Boot, RESTful API design, securing applications with Spring Security, and transitioning toward Microservices architecture.
