"Andreas really has an educational way of explaining OOP. During my time as a student, I appreciated the concrete examples given during class time and how Andreas took the time to answer my questions if I did not understand certain concepts. Without his well-prepared lessons, assignments and easy access as a teacher, I don't think I would have made it through the intensive training."

Andreas Olsson
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.
