What made the experience be great here at DataExpert is the structured lessons, accompanied by hands on assignment which I know extends the theoretical lessons exponentially, and It is one of the best ways to learn, especially online.
I would to Thank you all stuff its great im really doing a great things in my job
IMO most of the instructors were awesome, the content is tailored for all levels (from beginner to intermediate and somewhat useful even for advanced), the homeworks were insightful and the capstone is a great learning challenge. There were minor UX issues like homework 5 being forgotten. I also think the price is a bit high for underdeveloped countries, easily 1-2 salaries of the average engineer that doesn't earn in dollars. I only managed to do it because of the higher discount I was able to get
Zach made this experience great. I did enjoy the other instructors but nothing compares to Zach yapping. I’m so sad it’s over. Not sure what to do with myself now.
AI Engineering, Databricks and Snowflake bootcamps all finished. Over 15 weeks of learning back-to-back. Do the bootcamps if you want to hugely improve your skills, fill gaps in your knowledge and be inspired to do more. Don't do it if you're lazy or won't put in the work; you'll just be wasting your money.
Thanks for your great service which you are providing to all the learners. This is exceptional and great helpful for beginners, Job seekers
I love learning about the concepts
Lots of knowledgeable and hands-on content to jump on. Going to enroll into more learning paths.
I thank the team for putting all the efforts to build more data professionals. They bring real world experience and examples into the cohorts.
What I liked most is that you actually do the work, not just watch videos. Zach made us personal accounts in Databricks so we practice on the same tools companies use every day. That was huge for me because it feels like you are working at a real job, not doing some tutorial. The homework is where I learned the most. The Spark one gave us a broken pipeline and we had to fix it. It was hard but that is how you actually learn. You go through the code line by line, understand what it does, and then you start seeing ways to make it better. That does not happen if you just let AI write everything and never read it. Zach makes you do the work and explain what is going on. I like that. The more you practice the more things click. Good bootcamp, would recommend.
Higher level of knowledge is required to understand the teachings but the connecting dots that level is missing. As I felt the technique of code dry run is required at a slower pace may be by teaching assistants before jumping on project. Apart from that Zac has really cool experience from every data bases available till date. But needs a lot of rigorously focused mind from students.
Giving out real world examples and problem solving. Good depection of concepts through labs and a helping community
The introduction on real data systems - The free one enhanced my overall view of data infrastructure
Excellent content. Good tools
Dataexpert.io content is a real gateway for any data person with average/below average skill to look beyond/further. It basically shows the path or bridge the gap in multi retrospects. Gives us a peek into how are things get done in FAANG companies when zach was working. Absolutely Loved it
It was exciting to learn about ADAL. Cool tool!
Right now, I'm not always focused on data engineering (more enthusiastic about AI or ML), but the site's recurring free events (bootcamps, quizzes...) help me to better apprehend the field, understand how it interacts with other roles, and even acquire valuable knowledge. The platform is also expanding to other areas, like security or agentic AI on AWS (Besa cloud academy) allowing everyone to get into a learning path that will make them happy.
The content of the bootcamp was very, very rich in work experience related to data engineering. although the curriculum wasn't easy, it was awesome to go through it and made me feel alive
It has been a wonderful learning experience.
It’s a high-quality learning platform for anyone serious about data engineering. The courses focus on practical, real-world skills using modern tools like SQL, Spark, Airflow, and cloud data stacks, with hands-on projects that translate directly to the job. I purchased the all-access subscription because I couldn’t afford the bootcamp, and it has still provided tremendous value and depth. Highly recommended.
