Highly recommended

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.

Zach Wilson's AI Engineering Bootcamp

As a data platform engineer with two small kids at home, finding time for self-learning is a constant challenge. Between work and family, I needed a structured program that would make every minute count—and this bootcamp delivered exactly that.
What sets this course apart is that Zach isn't just an instructor; he's an engineer who has actually built things in the industry. That real-world experience shows in every module. The case studies aren't theoretical fluff—they're grounded in practical scenarios you'd actually encounter. The hands-on exercises are excellent and reinforce concepts in a way that sticks, even when you're learning in small windows of time between bedtime routines and work deadlines.
The format works beautifully: well-produced lectures that get to the point, followed by hands-on labs, assignments, and a capstone project that ties everything together. For someone transitioning from data engineering into AI engineering, this progression felt natural and built confidence along the way.
I also have to call out the platform itself. The auto-grading on assignments gives you immediate feedback, and the progress tracking helps you see momentum even when you're chipping away at the content in short bursts. These features matter when you're juggling a full-time job and a family—you need to know you're making progress.
If you're a working engineer looking to upskill into AI, especially with limited time, I'd highly recommend this bootcamp. It's one of the best learning investments I've made.

The content is more than great.
It covers so many interesting things.
Also, the student must do their homework and practice the topics. If you are someone who does your part in a course, that’s for you. I really loved it.

I do recommend it.

Thank you DataExpert Team!!!

Zach's ability to troll the group at the start of each call with his 'Can you hear me?' act never gets old ;p

Amazing teacher, don't f-around and go sign up, it will be worth it.

Exactly the practical context I've been missing

Dataexpert has been great - I have found it so useful to learn from those who have grinded away for years at the top companies. There are concepts I've learned from textbooks which I've sometimes questioned the practicality of (ETL vs ELT, true streaming vs micro batching), and Zach has been able to provide much-needed colour from real-world examples. Zach's been able to directly answer the questions that were floating around in my head, without me even needing to ask!
It's been very useful to hear how the big tech companies solve the cutting-edge challenges, but just as useful to learn which solutions are 'good enough' for most real-world scenarios.
The balance of high-level insight and pragmatic guidance on this course is well worth it.

Great value for time and money!

Zach is a great tutor. DE lessons were packed with valuable gems. The video lessons were easy to follow and understand. Instructions to set up coding environments and Discord participation, support from Zach's staff were all great. Highly recommend this course.
