Last week, for 4 days, the BackEnd Community within CGM participated in a very intense and interactive hybrid workshop with the Java Champion Vlad Mihalcea, called 𝐇𝐢𝐠𝐡 𝐏𝐞𝐫𝐟𝐨𝐫𝐦𝐚𝐧𝐜𝐞 𝐉𝐚𝐯𝐚 𝐏𝐞𝐫𝐬𝐢𝐬𝐭𝐞𝐧𝐜𝐞.

It was an amazing experience and it clearly must be done again on the next level. So, Vlad, thank you for everything that you gave to us in these 4 days, from shared knowledge to good vibes. And, as you already know, our doors are always open for you when you get to Iași.

What better way to strengthen one's Hibernate skills than with a course in High-Performance Java Persistence with none other than the world-renowned expert, Vlad Mihalcea!

In a 4-part series, each 4 hours long, densely packed with everything from "best practices" to "biggest pitfalls", developers all around Cloudflight got nothing less than wisdom from the best.

We thank Vlad for this great experience and wholeheartedly recommend him to anyone else willing to dig into the nooks and crannies of High-Performance Java Persistence.

Every time I had heard that some app needs to be fast, I would have run away from Hibernate. Well, not anymore! After attending Vlad's High-Performance Java Persistence course, I changed my mind.

It was well structured, focused on performance and day-to-day usage. There were lots of details and small things that can really make a huge difference.

Everything was backed up by code examples. Vlad is a smart guy with lots of patience, and he's passionate about technology.

Learn the power of Hibernate! Use it properly!

I've been using Hibernate for over 8 years in various projects, and I was thinking "what's more to learn about it?". Well, it turns out I was wrong. I've learned a lot after attending Vlad's training.

It was a very educative and enlightening course, backed up by a lot of code samples, answered questions, do's and don'ts in the Hibernate world. There's a huge difference between using Hibernate and using it right.

As Java developers, we all use JPA and inherently Hibernate at one point in time in our projects. Sometimes it happens that some of us just use and abuse this technology.

The presentation has the right topics, order and proper information to get the beginners and the “lost” intermediate user on the right track. You are a senior, and you wonder if it’s the right thing for you? Well, you can get under the hood and understand the underlying mechanisms and implementations used throughout the framework. Moreover, you will learn about advanced topics like caching, locking mechanisms and concurrency control.

I strongly believe that this is a great all-around training when it comes to ORM concepts.
