"Humourous, friendly presenter, open and willing to answer questions, pace is speedy and focused (I feel very mentally drained and overwhelmed by this point of the course). I appreciate the regular breaks to allow for rest periods but not sure about tying them into exercise times as it is easy to merge them. Explanation wise was fantastic, enjoy the simple examples with dogs, books, calculators etc. Rated 5 out of 5."

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.
