Hi!
My name is Vlad Mihalcea, and I’m a Java Champion. I wrote the High-Performance Java Persistence book, which became one of the best-selling Java books on Amazon.
I'm currently developing the amazing Hypersistence Optimizer, and in my free time, I develop various open-source projects (e.g. Hypersistence Utils and FlexyPool) and answer questions on StackOverflow.
Blog
I've been blogging since 2013 about Java, JPA, Hibernate, Spring, SQL, and database systems (e.g., Oracle, SQL Server, PostgreSQL, MySQL).
Book
I wrote and published a book called High-Performance Java Persistence, which has been read by thousands of Java developers all across the world.
Course
I've been publishing several video courses based on my High-Performance Java Persistence training material, which you are going to love.

If you are interested in having me reviewing and optimizing your enterprise applications, then you should definitely contact me.
Conferences
I'm speaking at software conferences about Java Persistence, Hibernate, database systems, and SQL.
StackOverflow
I've been answering thousands of questions about Java, JPA, Hibernate, Spring, and SQL on StackOverflow.
GitHub
Besides open-source projects (e.g., Hibernate-Types, FlexyPool), all the source code on my blog, book, and courses is hosted on GitHub.
Tutorials
With over 300 articles, my SQL and Hibernate tutorials are some of the most comprehensive resources on these topics.
