About me

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 20+ 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 look forward to showing you how to use Hibernate to implement high-performance applications.
