"One of the things I appreciated about Andreas as a teacher was the ability to meet everyone at their level in a permissive and understanding way. Whether it concerned questions that were far beyond what we were talking about right now or things that we had already talked about before, there were no questions that felt stupid, but we participants were seen as intelligent, thinking people who have the capacity to filter the information ourselves. That respect for us and our journey meant a lot to me and I think it was a big part of why the training worked so well."

Expertise through Active Learning
Java and the Spring Framework have been my core focus for over 20 years. Today, my mission is primarily to help organizations step into the future by integrating intelligent agents and AI-driven features into modern Java systems.
Actlea stands for Active Learning – the philosophy that programming is best learned by writing code, not by watching slides. My workshops focus on intensive, hands-on exercises designed to solve real-world problems.
I deliver proven training concepts globally across all timezones. While I specialize in remote delivery, I love to travel for onsite workshops. My modules are ready for immediate impact but can be tailored to your team's specific requirements.
