RegistrationService.java

// Module 5 → Module 6: Spring Boot → Microservices
@Service
public class RegistrationService {
@Autowired
private EventClient eventClient;

          public Registration register(Long userId) {
        

          var event = eventClient.getById(id);
        

          return repo.save(new Registration(userId));

// AI pair programmer

You need an idempotent consumer here. Check for duplicates by correlationId before saving.

One Project — The Entire Journey

CRM Registration System
from Console to Microservices

You don't start a new training project every time. One real product evolves through all 9 modules — just like in real-world development.

Module 1-2

Console Application

Java Core · Gradle · Git · JUnit

First version of the registration system. Console, files, basic data structures.

Module 3

Containerization

Docker · Docker Compose

The project runs reproducibly in a container. Foundation for the next layers.

Module 4

Database

PostgreSQL · JDBC · Liquibase · Transactions

Real data persistence. Concurrent registrations, transactional safety.

Module 5

REST API with Spring Boot

Spring Boot · JPA · OpenAPI · MockMvc

The monolith becomes a backend service with a documented API.

Module 6

Microservice Architecture

DDD · API Gateway · Feign · Resilience4j · Vault

Decomposition along domain boundaries. Parallel calls, Circuit Breaker, Outbox.

Module 7

Kubernetes + Observability

Helm · Prometheus · Grafana · Jaeger · SLI/SLO

Deployment to K8s. Tracing, metrics, diagnosing fan-out scenarios.

Module 8

Kafka and Events

Kafka · Saga · Outbox (Debezium) · DLQ

Async processing. Idempotent consumer, Saga orchestration, DLQ.

Team Development

Real Team Collaboration
from Day One

In the final modules you plan tasks, do code reviews, work with Git workflow and an AI pair programmer — just like on a real team.

⚙

Git Workflow & PRs

Feature branches, pull requests, code review — standard team workflow from the very first module.

🤝

AI Pair Programming

A CLI agent as your second developer: generates tests, refactors code, helps with boilerplate. You're the lead.

📋

Task Planning

Story Points estimation, Sprint Planning, backlog management — skills expected on real projects.

🔍

Code Review

Discussing architectural decisions, checking code quality, understanding the "why" — not just the "how".

🚀

CI/CD Pipeline

GitHub Actions, JaCoCo, Checkstyle — builds don't break, coverage grows, style is enforced automatically.

📡

Team Observability

Metrics, traces, SLI/SLO — you see how the system performs and can explain it to the team.

Final Module 9

Career Track:
Real Development

In the finale you don't just prepare for interviews. You package a real project — the same one you built hands-on from console to Kafka — into your portfolio and resume. You present technical decisions with business context.
