"I'm a senior software engineer whose main languages are TypeScript and Python. I recently joined a new team that's very Java-heavy, and I spent a long time trying to find something that was the right skill level for me to learn Java. Everything I found seemed too basic and was explaining things like the concepts of variables, or assumed too much knowledge and was too difficult. I'm so pleased to have found Actlea; it was precisely what I needed to get up to speed. Andreas was great and found an excellent balance of explaining the language-specific features while assuming some prior knowledge. If you're already familiar with one or more languages and need to get up to speed quickly in Java, this is the course you're looking for. The cadence and pacing of the class is perfect, engaging, and thorough, and I have the tools I need now to delve deeper into this language and make an impact on my team. Thanks, Andreas, for putting this together!"

Curriculum & Highlights
Challenges we address
"How is testable code written using TDD and JUnit 5 as a natural part of the development process?"
"How are the Collections Framework and Generics mastered to handle data professionally?"
"How is the transition made from basic loops to declarative programming using modern Streams and Lambdas?"
With solid craftsmanship as a foundation, the next natural step is mastering the ecosystem's powerhouse in 'Spring Boot Jumpstart: Essentials'. →

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.
