About

I'm Henry Lim. I have worked in BI and analytics for about ten years, in several industries, and my background is in industrial engineering.

I write for BI developers, analysts, and analytics engineers who know SQL and a BI tool well and now work with lakehouse platforms and AI tools. Each post takes one problem from that work and solves it with code you can run.

Every example is built from scratch on synthetic data, and the code is published with the post. Product details are checked against the vendor's documentation, and each post says when that check was last done.

The name comes from wright, an old word for a maker, as in shipwright or playwright.
