These are the options we give you
At your place or ours?
Everyone learns at her/his own pace. We provide both in-house training and public training throughout Europe - whatever suits your team best. When 3 or more developers are attending, a custom training is often more economical. Contact us for more details.
You'll get courseware
Every workshop is accompanied with official Yireo coursematerial. Attendees are sent a digital version of this material after the training. It contains slides, comments and references. Additionally, our GitHub repos contain numerous more code samples.
Online classrooms
Online trainings are also our training: Via Zoom or Google Hangout sessions, our teacher is able to connect with your team. The benefit here is that the team is able to connect from various places itself as well, timeframes are more flexible. Afterwards, a video recording will be shared with all attendees for reference.

Jisse explains the relevant technology in an understandable way that is very useful in practice. The training is intensive, at a high level and of great added value because important concepts are made clear and you receive many useful tips. Oscar Hilbelink (Madia)
I really enjoyed the Magento 2 Hyvä Theme Development course. The information is useful and well-structured. I appreciated the extensive practice, which helped me understand how to develop a frontend using Hyvä. Jisse is easy to listen to and engaging, which made the course even better. Nadezhda Ivanova (HYPR)
As a newcomer to the Magento world, the Magento academy has given me a solid foundation for Magento 2. I benefit greatly from this in my daily work as a Frontend Developer.
