Hi, I'm Andreas Kretz

Senior Data Engineer, Educator, and Founder of the Learn Data Engineering Academy

I am a Senior Data Engineer and Trainer, tech enthusiast, and a father. I have been passionate about Data Engineering for over a decade.

First as a self-taught Data Engineer and then Data Engineering team leader in a large company. When I realized how much need there was for training in this area, I followed my passion and started my own Data Engineering Academy.

Since then, I helped over 2,000 students achieve their goals.

I'll show you how you too can become a successful Data Engineer or use Data Engineering in your job.

My proven training program has already helped over 2,000 students achieve success! They work at:

Data Engineering is changing fast. The engineers who stay ahead are the ones who keep building.

AI is changing what tools engineers use. But experienced judgment about what to build, why, and how to make it survive scale is still entirely human.
That is what this Academy teaches.

Learn Data Engineering content is based on the latest market standard and is constantly being expanded.
With our expertise, we have already boosted the careers of
tens of thousands of people online.

Everything is Data Engineering. Even AI.

This track teaches you how modern AI systems actually work, starting from embeddings, to semantic search, to local RAG agents that run 100% on your machine. No cloud. No guesswork. Just solid, hands-on engineering.

You’ll build real tools and understand every component along the way. From first vector to fallback logic, this is AI for Data Engineers who ship.
