Tools Built for Power BI Engineers
The pbiexpert flywheel connects learning, development, and diagnostic auditing. We build tools that make engineering reliable Power BI systems faster and more repeatable.
DAXQuest
Interactive DAX Simulation Platform
Learn Power BI and DAX by solving real engineering problems.
The flagship interactive learning engine built by pbiexpert. Run DAX against real star schemas, test filter context transitions in real time, and progress through 47 challenges across 6 modules.
BIKit
Developer Tooling for PBIP & TMDL
Build, format, and version-control Power BI more effectively.
A suite of developer utilities designed for modern Power BI engineering workflows. Enables teams to transition from binary .pbix files to plain-text Tabular Model Definition Language (TMDL) with Git version control.
powerbi.dev
Semantic Model Static Analysis Engine
Analyze Power BI semantic models and identify engineering debt.
An automated static diagnostics engine that profiles VertiPaq memory footprints, detects high-cardinality bottleneck columns, identifies bidirectional relationship cascades, and flags unoptimized measures.
The pbiexpert Engineering Flywheel
We use our diagnostic tools (powerbi.dev) and developer utilities (BIKit) in our client Health Checks, while codifying our architectural findings into DAXQuest and Engineering Notes. This feedback loop ensures our practice remains grounded in production Power BI engineering.
