Intro

In this talk, Juan, Analytics Engineer and author of Fundamentals of Analytics Engineering share his professional journey from studying psychological research in Colombia to becoming one of the first analytics engineers in the Netherlands. We explore the evolution of the role, the shift toward engineering rigor in data modeling, and how the landscape of tools like dbt and Databricks is changing the way teams work.

You’ll learn about:

• The fundamental differences between traditional BI engineering and modern analytics engineering.
• How to bridge the gap between business stakeholders and technical data infrastructure.
• The technical "glue" that connects Python and SQL for robust data pipelines.
• The importance of automated testing (generic vs. singular tests) to prevent "silent" data failures.
• Strategies for modeling messy, fragmented source data into a unified "business reality."
• The current state of the "Lakehouse" paradigm and how it impacts storage and compute costs.
• Expert advice on navigating the dbt ecosystem and its emerging competitors.
