Dataexpert has to be one of the best resource available in data. Their free resource itself is great and no doubt, their paid content will absolutely be worth the money.

Having prior experience working in the data domain, Zach's lecture felt highly relevant. His course content was strong and as per industry standard. His industry experience really speaks for itself as he shares his approach tackling different problems faced while working at Big Tech. The assignments were challenging and rewarding, giving great insights and hands-on the theoretical concepts taught. Highly Recommend the course for data folks looking to level up their skillsets.

Amazing content and instructor Zach find the perfect balance between theory and practice.

A lot of content with guided exploration, yet there is still some tweaking around, and you need to carefully go back in order to debug but that's part also of the job. Thank Zach for providing content out there
