Java Engineering Masterclass

Java Engineering Masterclass

From architecture to deployment in 2 days

In modern software ecosystems, Java continues to anchor enterprise-scale systems — yet excellence now requires mastery far beyond core syntax. Professionals must architect maintainable systems, design asynchronous operations, build secure REST APIs, and ensure seamless deployment through CI/CD pipelines. This advanced two-day course, led by an instructor with over 30 years of industry experience, emphasizes practical, production-oriented approaches rather than academic exercises. Participants will explore the architecture and engineering patterns demanded by real-world Java solutions.

Learning Outcomes

Participants will be able to:

• Design scalable, maintainable Java application architectures.
• Implement asynchronous processing flows using modern Java concurrency.
• Build efficient, secure RESTful APIs.
• Integrate advanced security principles into Java systems.
• Establish automated CI/CD pipelines for Java applications.
• Apply architectural principles that enhance observability, scalability, and maintainability.

Prerequisites

• Strong proficiency in Java (Java 8 or higher).
• Experience developing backend systems (preferably with Spring Boot or similar frameworks).
• Familiarity with RESTful APIs, security concepts, and build tools (Maven or Gradle).
• Basic understanding of Git and CI/CD concepts.
