"I had the honor of having Andreas as a teacher during a 12 week Java program for Brights. During these weeks we learned the basics of Java but also more advanced Java. Would really recommend Andreas for the great competence he possesses but also for his patience. He always answered the questions that we students had and was very patient when required. Andreas always has a smile on his face and he is passionate about teaching, which you can clearly see. I always felt safe talking to Andreas when I needed help and he was always there to support. He is simply one of the best teachers I have ever had!"
RESTful APIs with Spring Boot
Build and consume REST APIs with Spring Boot 4. Master @RestController, Spring Data JPA, and the modern RestClient through hands-on coding.
The ability to build complete REST APIs with Spring Data JPA and consume external services using RestClient in a professional manner.
Developers wanting to practically implement and integrate REST services with databases and external APIs in 2026.
Basic knowledge of Spring Boot equivalent to 'Spring Boot Jumpstart: Essentials' is required to dive deep into API development.
Curriculum & Highlights
Challenges we address
"How are @RestController and Spring Data JPA implemented to create efficient and searchable CRUD APIs?"
"How is the new RestClient used to consume external APIs in a secure and type-safe way?"
"How is data mapped between database models and API contracts to avoid tight coupling?"
With the basics of API development in place, the next natural step is to dive deeper into how to handle persistence and optimize data access in 'Mastering Spring Data & Persistence'. →

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.
