superb, outstanding experience with the bootcamp
By Iver Samuel Medina B.
The videos and step by step demos provided great explanations. Zach doesn't just tell you the steps, he explains why they are necessary. The assignments were challenging, but they helped me learn a lot about troubleshooting and problem solving
By Taya B.
Great content! Zach is able to write about extremely important day to day data engineering that you hardly find content about. He also challenges the common sense and wants to keep solutions simple and modern. Highly recommended!!
