Student Reviews & Testimonials

"Truly outstanding—no doubt about the quality of the content. An excellent opportunity to learn from an expert Data Engineer with hands-on experience managing massive datasets. The most valuable part was seeing how he solved real-world challenges for leading Big Tech companies and Tips & Tricks he shared in his shorts."

"Great course for beginners. I'm a data analyst interested in data engineering so this course is a really good introduction. It's nice that Zach is slowing down the pace and explaning in detail."

"Not clear of the course, its very vague. Please structure the course clearly"

"I feel like the program is designed for beginner level. So I have moved to community boot camp. Where i found out that i could enriched my skills. However the free beginners boot camp is amazing and focus on fundamental"

"You will learn a lot in this free bootcamp."

"Very good introduction for the beginners"

"The curriculum covers key topics like data modeling, Spark, Kafka, and Flink in a beginner-friendly style with real-world context. The epic Discord community is always there to answer questions and clear doubts. It also keeps learners motivated as they see peers completing the course and proudly sharing their certificates."

"From 0 to a 100 real quick"

"Am catching up really fast as am forced to do a little search here and there along to figure some stuff out rather than spending lots of time on very simple basics. The experience data engineering path delivered here is fulfilling. Thanks 👍🏾"

"Awesome Experience"

"easy to follow"

"If your just beginning in your data engineering journey, this is the play to start, great introduction to the subjects!"

"Easy to follow, clear and direct to the point!"

"I recommend this course to all beginners in DE"

"Despite the tutors advance skills, this course was well curated to give a soft landing to beginners. I love the raw and the hands on/project format. Thanks Zach"

"This bootcamp was truly outstanding. Zach has a wonderful gift for explaining complex concepts in ways that work for students at every level - whether you're a complete beginner or have some prior experience"

"A masterclass in practical data engineering. This isn't just theory, it's a deep dive into the applied strategies used to handle data at scale. The Zach's firsthand experience with massive datasets in big tech is invaluable. The real goldmine was the collection of proven tips and clever optimizations shared throughout the course."

"Zach’s course has been one of the most practical and easy-to-follow learning experiences I’ve had. The amount of value packed into a free course is truly impressive and speaks to the quality and effort behind the program. It makes me curious and excited to imagine what the premium version of this content would look like. This kind of teaching not only builds skills but also inspires confidence, which is why I am eager to continue learning under Zach’s guidance."

"Very good content"

"Not for beginners, no clear structure, no attempt to address topics from first principles. Learners need foundational -level SQL and Python. Knowledge to follow. ."

"I enjoy the community bootcamp it's given you a general idea about data engineering and important topic like data modelling spark kafka flink. no need to pay for courses that give poor stuff, thank you zack for this amazing journey if you want to learn this stuff in cloud i highly recommend to buy zack's courses"

"The content is well-structured. I took the free community bootcamp, and it clearly depicts the importance, impact, and reach of data engineering. Every part of it is very well documented, from the setup guides to get started to the final module, and the AI grader is an excellent tool for those who complete it independently. The explanation of the topics is very concise and helps in understanding the real use of each technique. Highly recommended!"

"Used to be obsessed with tools, but this Boot Camp showed me what I should really think like as a data engineer!"

"it's great, although it does require a lot of personal research and diving into things with examples in order to clarify things, but it's very thorough and i love it"

"This course is amazing. You will learn a lot even if you are experienced Data Engineer."

"The Boot Camp: Community Edition gave me a solid foundation in Data Engineering. It covers essential topics like Data Modeling, Spark, Kafka, and Flink in a way that's beginner-friendly but still deep enough to build real skills. I appreciated how hands-on the experience was—especially the AI grader and the well-structured modules. If you're serious about getting started in data engineering without spending a fortune, this is a great place to begin."

"What stood out was the breadth of the curriculum. This bootcamp is perfect for leveling up on all key aspects of modern data engineering and building confidence from ingestion to visualization. Highly recommended!"

""Great course! It was my first time learning about data modelling, and I found it really fun and engaging""

"Great course for beginners. This course covers the foundation in depth."

"This course is excellent. Don't let the fact that it's free fool you—the content is anything but basic. The assignments are challenging, and I learned a tremendous amount."

"Its been an awesome experience taking the course"

"Highly recommended to any data engineers who want to upgrade themself. Homework's are challenging, and its not like another certification where you can sleep walk some multiple choice questions."

"Awesome course with both theory concepts and hands on examples, well structured and presented. Great great work"

"An excellent instructor who teaches data engineering by combining theory with real-world experience from big tech."

"Is a privilege. TOP!"
