Modern code. Better performance. More joy in development.
Hands-on trainings on modern Java features, performance, concurrency & more –
as an in-house training at your company or virtually for your team.
From the latest Java version to the Stream API: find the training that gives your team the biggest leap.
These Java courses bring your team up to date – compact and practice-oriented.
For teams catching up on several version jumps at once: These courses combine two or three Java versions in one training – more efficient than booking them separately.
Focused Java education on specific technologies – as a 1- or 2-day training.
All trainings are interactive and hands-on: short theory impulses, followed by practical exercises with examples from real projects. The goal: knowledge that shows up in your code and daily work right away.
During the training, I address your individual challenges. If the group wishes, we go deeper into exactly the topics that really help you in practice.
I flexibly adapt the pace to the group’s level of knowledge. Better to truly understand less material than to superficially tick off a lot – quality over quantity.
Not every training fits every team. Drop me a line about where you stand – which Java version you use and what you’re dealing with. I usually get back to you within 24 hours. If it makes sense, we’ll clarify in a short video call which course fits your team best.
Request a training for our teamI’ve been working with Java for over 20 years – as a developer, CTO, trainer, author, and speaker.
In that time, I’ve helped companies modernize complex Java systems, write performant code, and develop their teams sustainably.
With HappyCoders.eu, I’ve built one of the most widely read Java blogs in the German-speaking world, and I regularly speak at conferences and user groups.
My goal: to teach complex topics in a way that is understandable, practical, and immediately applicable.
