About the Author

My name is Thorben Janssen. I'm a consultant, trainer and the author of the Amazon bestselling book Hibernate Tips - More than 70 solutions to common Hibernate problems.

For the last 15 years, I have been using Hibernate and JPA in all kinds of projects. From small ones with very aggressive timelines to huge projects that had to handle thousands of users.

The requirements of these applications were very different and I learned that Hibernate provides good solutions for all of them. You just have to understand the features with their advantages and disadvantages.

I'm looking forward to showing you how to use Hibernate to implement high-performance applications.

Work with Me

Thorben not only excels with his knowledge about modern JPA API usage – he also consistently stresses the importance of knowing the underlying SQL technology.

After subscribing to the newsletter, it became clear that Thorben has a firm grasp on exactly the issues we were addressing. We signed up for the expert bundle which included the Hibernate Performance Tuning Online Training and the Advanced Hibernate Online Training.

As a result of the training, we confidently refactored our code to follow the patterns described in the training course and doubled the performance of some of our services.
