In 2011 I wrote a mini-course on mastering Magento which was listed on this page.
However, this course became terribly outdated and in addition I "left" the Magento ecosystem in 2021 when I joined Spryker.
If you're looking for an enterprise e-commerce platform that is also more modern and modular, I highly recomend you check out Spryker.
I speak at various international events every month and I'm regularly awarded as the best and most engaging speaker of the event. Send me your details and we'll get your event onĀ my schedule!
