Modern Java Fast-Track
Upgrade the codebase by mastering Data-Oriented Programming, Java 21, and Virtual Threads.
Knowledge to separate data from logic (DOP) and the tools to build type-safe, high-performance, and asynchronous applications.
For experienced Java developers and architects wanting to eliminate technical debt and build massively scalable systems with modern Java.
Professional Java experience is required; if the language is new, we recommend 'Java Jumpstart: Essentials' instead.
Curriculum & Highlights
Challenges we address
"How do you eliminate boilerplate and create immutable data using Records and Text Blocks?"
"How do you separate data from logic (DOP) using Sealed Classes and Pattern Matching?"
"How do you scale to millions of asynchronous tasks using Virtual Threads instead of reactive frameworks?"
With the architecture modernized, 'Functional Java: Lambda & Streams' is recommended to radically simplify data processing. →

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.
