I used to pay for overpriced courses…

I used to pay for overpriced courses that only taught the basics of ETL/ELT, but these free courses from Zach really opened my eyes and showed me that the job isn’t just about building pipelines and keep looking at them to ensure my career safety.

Best data ressource

Very instructive bootcamp (beginner and community). Real experiences from Zach. It's not for true novice or people who want to discover data. It's for people who knows already db, vocabulary, pratices etc..
I recommend.

The Best Breakthrough into modern Data Engineering

I’ve been following DataExpert.io for a while, and it’s been invaluable in my pivot from software engineer to data engineer. The content surfaced gaps in my skills and helped me close them fast. It’s compact, practical, and rich with advanced SQL and data warehousing techniques. I’m still working through the community bootcamp, but the value is already clear
