Spring Boot Web Development

Spring Boot Web Development

Empowering PHP Developers to Build, Deploy, and Scale with Spring Boot - 3 days

This foundational course in Spring Boot for Web App Development is designed specifically for PHP developers transitioning to Java and looking to build real-world, scalable applications. By focusing on remote development environments using VS Code's SSH plugin to connect to Linux servers, we eliminate the typical frustrations and limitations of local setups. This hands-on course equips you with the skills to go from development to deployment, providing you with tools and techniques actively sought after in the industry. Spring Boot’s simplified Java configuration for enterprise-level applications will give you the power to build, test, and deploy in a production-like environment, all while bypassing theoretical pitfalls.

Instructor Profile: With over 30 years of industry experience, your instructor brings a wealth of knowledge in enterprise application development, deployment strategies, and real-world problem-solving. No abstract academia—just industry-demanded skills, directly applicable to your day-to-day development tasks.
