Learning objectives

  • Optimize the JVM for maximum performance
  • Master advanced concurrency with Virtual Threads
  • Implement resilient microservices with Spring
  • Secure Java applications in production
  • Develop scalable cloud-native architectures
  • Analyze and tune performance in real-time
  • Produce production-ready deliverables

The Learni story

Founded by passionate learning and innovation experts, Learni's mission is to make professional training accessible to everyone, anywhere in the world. Our team operates in major hubs — London, New York, Boston — and internationally, to support talents and organizations in upskilling.

Don't let this gap widen

Why this program matters

  • Without expert JVM mastery, your apps lose 40% of performance, doubling server costs and tripling downtime.

  • Unmanaged concurrency bugs generate 30% additional dev losses, exposing you to security breaches costing on average 4M€ per breach according to Verizon DBIR.

  • Lacking cloud-native scalability, your projects stagnate against the competition, with 50% of senior Java lead devs stuck on obsolete monoliths.

  • Invest now to avoid these costly pitfalls and dominate production.

Program

Module 1Advanced JVM: Tuning and Profiling (VisualVM, JFR, GC)

Dive into the JVM internals, configure garbage collectors to reduce pauses by 70%, profile with VisualVM and JFR on real e-commerce app cases, perform practical memory tuning exercises, generate personalized optimization reports, everything to boost your performance from day one.

Module 2Expert Concurrency: Virtual Threads, CompletableFuture (Java 21)

Master Virtual Threads to scale to 1 million connections, code asynchronous flows with CompletableFuture, simulate high-load scenarios via JMH, debug deadlocks live, produce ultra-reactive concurrent services, with immediate feedback on your implementations for instant expertise.

Module 3Java Microservices: Spring Boot 3, resilience4j, Kafka

Build distributed microservices with Spring Boot 3 and resilience4j, integrate Kafka for event-sourcing, deploy in Docker containers, test resilience with Chaos Engineering, create a complete CI/CD pipeline, transform your monoliths into scalable architectures ready for Kubernetes.

Module 4Production Security and Performance: Quarkus, GraalVM, Observability

Secure with Spring Security OAuth2 and GraalVM native, optimize for zero-downtime with Quarkus, implement Micrometer/Prometheus observability, analyze production bottlenecks via exercises on real apps, deliver a final native and secure project, gain deploy-ready expertise.

Evaluation method

  • Daily technical quizzes, evaluated practical projects, internal Java Expert certification.

Learning method

  • Interactive pedagogy 70% hands-on, real business cases, personalized feedback.

Methods, materials and delivery

The Training Java Expert - Optimize JVM and Application Scalability program is delivered onsite or remote (blended-learning, e-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.

The trainer alternates between demonstrative, interrogative and active methods (through hands-on labs and/or scenarios). This pedagogical approach guarantees concrete learning that's immediately applicable at work.

Our method

Training quality, guaranteed at every step

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

  • Triple validation: technical, pedagogical, sectoral.
  • Minimum rating 4.8/5 over the last 12 sessions.
Step 2

You meet the trainer beforehand

30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.

  • Live briefing on goals and team context.
  • Veto right — we swap the trainer for free if needed.
Step 3

Content tailored to your context

No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.

  • Hands-on cases drawn from your stack and projects.
  • Program co-written then validated by your team.
Step 4

Continuous quality follow-up

Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.

  • NPS, knowledge quizzes and skills self-assessment.
  • Satisfaction guarantee: fully satisfied or free rework.

A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
