Description

This Camunda BPM course is built on my 5+ years of hands-on experience implementing Java and Camunda projects in variours companies. This course is your complete guide to mastering Camunda BPMN — from understanding the theory of process modeling to building and testing a production-ready application using Java and Spring Boot.You'll start by learning the fundamentals of BPMN: events, gateways, tasks, subprocesses, and how Camunda interprets process flows. We'll also cover decision modeling (DMN), variable scopes, and scripting with JavaScript and FEEL.Once the foundation is set, we'll move into hands-on development — building a real workflow automation system that simulates a full banking deposit process. Along the way, you’ll integrate custom business logic, write unit and integration tests, use REST APIs, and deal with real-life edge cases like validation errors and user decisions.This course is designed as a comprehensive and evolving guide to Camunda and workflow automation. It already includes in-depth lessons on BPMN, DMN, Java, Spring Boot, and real-life project examples.Whether you're a backend developer, QA engineer, analyst, or architect — this course will give you the skills and confidence to use Camunda in real projects.By the end of the course, you'll be able to:Design and execute BPMN workflowsModel decisions using DMNUse Camunda with Spring Boot and JavaWrite testable, maintainable Camunda logicBuild ready-to-deploy process automation solutionsNo prior BPMN experience required — we explain everything step by step.
