I am a Java Champion, CEO of Hypersistence, JPA expert, and one of the top Hibernate ORM committers.

I wrote hundreds of articles about Hibernate on my blog and I'm the author of the amazing Hypersistence Optimizer, the ultimate JPA and Hibernate performance optimization tool.

I also wrote the High-Performance Java Persistence book.

I enjoy going to conferences and talking about topics that I'm really passionate about, like high-performance database systems, transactions, concurrency control, or distributed systems. Here are some videos from some of the conferences I spoke at.
