Olga Berezovsky positions herself as a high-level strategic architect of data culture, moving far beyond the technical mechanics of SQL to focus on the human-led definitions that make data useful. Her content strategy centers on the critical "Data Foundations" layer, frequently arguing that AI and self-serve tools are destined to fail without rigorous, human-maintained business logic and semantic clarity. She is notable for her counter-intuitive stance on the AI hype cycle, asserting that as code generation becomes commoditized, the role of the analyst shifts from builder to essential decision enabler and context engineer. Her work represents a sophisticated intersection of technical skepticism and organizational leadership, where she bridges the gap between raw engineering and the nuanced business instincts required to prevent data from becoming a "house of cards."

Most companies think they have a data problem. They actually have a vocabulary problem.
I recently spoke with a Head of Data who was frustrated that their new AI agent was hallucinating revenue numbers. The model was technically perfect. The SQL was valid. The infrastructure was world-class.
The problem? The company had four different definitions for "Revenue" across four different departments.
When the model looked at the warehouse, it didn't see a single source of truth. It saw a civil war.
This is the "Context Gap" that no LLM can bridge on its own.
We often treat data engineering as a plumbing problem—getting bits from point A to point B. But as AI takes over the actual writing of code, the role of the engineer shifts. It moves from being a plumber to being a translator.
If you don't define what a metric means in plain English, the AI will just make its own guess. And in data, a guess is just a bug with a better personality.
