"I had the honor of having Andreas as a teacher during a 12 week Java program for Brights. During these weeks we learned the basics of Java but also more advanced Java. Would really recommend Andreas for the great competence he possesses but also for his patience. He always answered the questions that we students had and was very patient when required. Andreas always has a smile on his face and he is passionate about teaching, which you can clearly see. I always felt safe talking to Andreas when I needed help and he was always there to support. He is simply one of the best teachers I have ever had!"

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.
