Course Overview

Designed for professional backend engineers targeting senior and staff-level roles. Deep-dive into JVM heap/stack memory layout, low-latency garbage collection (G1GC & ZGC), Java 21 Project Loom Virtual Threads, Spring Boot 3 auto-configuration, resilient JPA persistence, and Docker microservice deployment.

What You Will Master

• Master JVM memory architecture, class loading, escape analysis, and JIT compilation. • Tune modern garbage collectors (G1GC, Generational ZGC) to achieve sub-millisecond pauses. • Scale concurrent systems to 1,000,000 tasks using Java 21 Virtual Threads without carrier pinning. • Architect enterprise REST APIs and resilient JPA persistence in Spring Boot 3. • Prevent production concurrency bugs: safe publication, happens-before guarantees, and lock-free algorithms.

Prerequisites

Intermediate Java, basic multithreading concepts, SQL fundamentals, and experience building web applications.
