FWIW, the article mentions the book "Designing Data-Intensive Applications" by Martin Kleppmann. I wanted to throw out my own endorsement for the book, it's been instrumental in helping me design my own fairly intensive data pipeline.
Reading it pushed me from thinking in terms of what I had worked with to building systems based on what was needed.
I cannot recommend it highly enough, for pretty much anyone in {frontend, backend, data science, etc}.
Initially I thought you were withdrawing your former endorsement.
