"My name is Rabia and I participated in the Java Developer course with Andreas starting January 2022 after 20 years in the banking and finance industry. Previously had no experience whatsoever in the IT world, but chose the track with the digitization the world is going through. The course was incredibly broad & intensive and gave a good overview. When the course was over, I was hired by Capgemini as a junior developer. During the course I probably complained many times about how much information it presented, but I have benefited greatly from everything I have been taught. I continue to learn every day but have an understanding that still amazes me when I realize how much I brought with me. Thanks Andreas for everything! The course has given me the opportunity to pursue a new career in a new industry that I love. The change has given me new energy and opened up new doors. I am so grateful!"

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.
