This course covers all the essential parts of Spring Boot 4
- I work as a Senior Java Developer and Solution Architect, and I know what topics are essential in the field
- I introduce all the concepts in a logical order so you quickly get up to speed
- I don't waste your time teaching you material that is hardly ever used in real-life (like Aspected Oriented Programming)

I show you real code, and I don't waste your time by live coding
- I illustrate each section with a new working application that you can check out and run on your own computer.
Course is suitable for total beginners, but also for developers who have worked with Spring Boot
- Course gives you a systematic understanding of both frameworks - Spring Framework and Spring Boot, and you need to understand that to work as a Senior Software Engineer one day
I show you how you can use ChatGPT or Copilot to move faster while still learning everything important
- I teach you all the essential parts about Spring Boot in this course.
- However, now and then, I point out what situations you can handle with an AI like ChatGPT or GitHub Copilot
I have included practical challenges
- Each lecture is accompanied by a personal challenge that I have crafted for you to gain an understanding of the main concepts of the section.
- I also provide complete solutions for all the challenges and explain them in separate videos - so you won’t have to be afraid that you get stuck solving any of the challenges.

Total beginners who want to learn Spring Boot from scratch
Who have already coded on Spring Boot but want to understand how the framework works
Intermediate students who want to learn how to utilize the full power of Spring Boot
