Prior professional Java development experience is required before joining.
Completion of Modern Java Programming Intermediate or a minimum of two years of professional Java experience is needed.
Confident working knowledge of Spring Boot, REST APIs, JPA, Maven, and Git is expected.
A laptop with Java 17 or later, IntelliJ IDEA, Docker, and Git installed is required.
Learners should be ready to work across microservices, Kafka, and cloud-native architectures.
Course Overview
What this course is about
The senior Java programme. Architected for engineers who want to lead.
This course takes you from solid Java engineer to cloud-native systems designer through microservices architecture with Spring Cloud, real-time event streaming with Apache Kafka, container orchestration with Docker and Kubernetes, and enterprise security with Spring Security and OAuth 2.0.
You won't just learn the tools. You'll build a complete, deployed cloud-native microservices system reviewed by an expert mentor at every stage that serves as the definitive portfolio project for senior Java engineering, tech lead, and solutions architect roles.
At ITLearnner, we focus on clarity, structure, and confidence. Every session adds a production-grade capability to the system you're building and every decision you make is one you'll be able to defend in any technical interview or architecture review.
Curriculum
01
Microservices Architecture and Spring Boot
Learn microservices design principles service decomposition, bounded contexts, and inter-service communication and apply them to scaffold your first production-ready Spring Boot microservice that will form the foundation of your capstone system.
02
Spring Cloud and Service Discovery
Learn Spring Cloud infrastructure components Eureka service registry, API Gateway routing, and load balancing and apply them to connect your microservices into a discoverable, routable system.
03
Event-Driven Architecture with Apache Kafka
Learn Apache Kafka core concepts producers, consumers, topics, partitions, and consumer groups and apply them to replace synchronous service calls with asynchronous event streaming between your microservices.
04
Containerisation with Docker
Learn Docker fundamentals Dockerfiles, image builds, container networking, and Docker Compose and apply them to containerise every microservice in your system and run the full stack locally with a single command.
05
Kubernetes Orchestration
Learn Kubernetes concepts Pods, Deployments, Services, ConfigMaps, and Ingress and apply them to deploy your containerised microservices to a Kubernetes cluster with production-grade resource configuration.
06
Enterprise Security with Spring Security and OAuth 2.0
Learn enterprise API security patterns JWT authentication, OAuth 2.0 authorisation flows, and Spring Security configuration and apply them to secure every service endpoint in your microservices system.
07
AWS Deployment and JVM Performance Tuning
Learn AWS deployment for containerised Java applications ECS, ECR, and CloudWatch and JVM performance tuning with heap sizing, GC strategy, and profiling, and apply them to deploy your system to AWS and benchmark its performance.
08
TDD, System Design, and Capstone Presentation
Learn test-driven development at the service level unit tests with Mockito, integration tests with Testcontainers, and contract testing and apply them to your complete cloud-native microservices capstone, which you will present and defend in a live architecture review.

Frequently asked questions
1
What level of Java experience do I need before joining this course?
This course is designed for developers who already have working Java knowledge — you should be comfortable writing classes, working with collections, and understanding inheritance before you join. If you are new to Java, the ITLearnner Python or Java Essentials courses would be a better starting point.
2
How is this course different from an introductory Java course?
This advanced programme goes well beyond syntax and basics. You will cover Java concurrency, advanced generics, functional programming with streams and lambdas, JVM internals, performance tuning, and architectural patterns. The focus is on writing production-quality Java code that can be maintained, tested, and scaled in professional environments.
3
Will this course cover Java 17 and later LTS versions?
Yes — the course covers modern Java features from Java 11 onwards including records, sealed classes, pattern matching, text blocks, and the latest stream and functional programming enhancements. Both Java 17 and Java 21 LTS features are addressed so you are working with the versions most commonly adopted in enterprise settings.
4
Does this course cover Spring Framework or just core Java?
The course focuses primarily on advanced core Java — JVM behaviour, concurrency, design patterns, and clean code practices. Spring is referenced in the context of architectural decisions and dependency injection principles, but deep Spring coverage is a separate specialisation. This course ensures your Java foundations are strong enough to excel in any framework.
5
Are there practical coding projects or just theory lectures?
Every topic includes hands-on implementation. You will build concurrent applications, design and refactor with patterns, optimise JVM performance using profiling tools, and implement functional pipelines with streams. The course is structured so that you leave with code you wrote and can demonstrate to employers.
6
Will this course help me prepare for Java professional certifications?
Yes — the depth of coverage is directly aligned with the Oracle Certified Professional Java SE Developer examination. Topics such as generics, lambdas, streams, modules, and concurrency are all core exam areas, and ITLearnner provides exam-focused guidance alongside the practical content.
7
What development tools will I use during the course?
The course uses IntelliJ IDEA as the primary IDE, alongside Maven or Gradle for build management, JUnit 5 for testing, and JProfiler or VisualVM for performance analysis. These are the tools used by Java developers in professional teams, so the course environment mirrors real-world working conditions.
8
How does this course address clean code and software design principles?
A dedicated section covers SOLID principles, design patterns (creational, structural, and behavioural), and refactoring techniques with real legacy code examples. You will practise identifying code smells and applying systematic refactoring, which is one of the most valuable skills for senior Java developer roles.
9
Is multithreading and concurrency a major part of this course?
Yes — Java concurrency is one of the most challenging and important areas for advanced Java developers, and it receives significant course time. You will cover the Java Memory Model, thread safety, the Executor framework, CompletableFuture, and reactive programming concepts, all with practical exercises designed to expose and resolve common concurrency bugs.
10
What kinds of roles will this course help me progress into?
This course prepares you for senior Java developer, Java architect, and technical lead roles. It is also highly relevant for developers moving into backend engineering, microservices architecture, and platform engineering positions where deep JVM knowledge and clean design skills are critical differentiators.
