In this podcast episode, I’m joined by Simon Späti, long-time BI and data engineering expert turned full-time technical writer and author of the living book Data Engineering Design Patterns.

 We talk about:

• His 20-year journey from SQL-heavy BI to modern Data Engineering
• Why switching from employee to full-time author wasn’t planned, but necessary
• How he uses a “Second Brain” system to manage and publish his knowledge
• Why writing is a tool for learning, not just sharing
• The concept of convergent evolution in data tooling: when old and new solve the same problem
• The underrated power of data modeling and pattern recognition in a hype-driven industry

Simon also shares practical advice for building your own public knowledge base, and why Markdown and simplicity still win in the long run.

Whether you're into tools, systems, or lifelong learning, this one’s a thoughtful deep dive.
