Camunda Training Course for Developers

The course is largely aimed at Software Developers but will also be beneficial for technical project managers, business analysts and software testers. We're also happy to tailor a bespoke course for your organisation in order to make sure the content and delivery is relevant and appropriate for your project requirements.

An understanding of software / web / enterprise applications and / or business systems and some exposure to coding with a technology such as .NET, Java, JavaScript, Python, C++ would be strongly recommended.

This Camunda for Developers course is available for private / custom delivery for your team - as an in-house face-to-face workshop at your location of choice, or as online instructor-led training via MS Teams (or your own preferred platform).

Get in touch to find out how we can deliver tailored training which focuses on your project requirements and learning goals.
