Power BI & Microsoft Fabric Architect | Supply Chain → Microsoft Fabric → AI-Ready Semantic Layers
This README is the short version. The portfolio has the full story: the IKEA-scale Fabric platform, a case study for every open-source tool, and what I am building toward in the AI era of enterprise BI.
- Microsoft MVP for Power BI and Microsoft Fabric, every year since 2022
- I architect, build, and look after IKEA's enterprise Fabric analytics: 30,000+ users, billions of rows across 15+ semantic models powering 30+ reports
- Copilot and AI agents answer from these models, so I keep them governed, documented, and source-controlled. I also lead how my team uses AI in development: Claude and Copilot are part of daily work, and I have started learning and actively using the Power BI Desktop Bridge and the Skills for Fabric agent skills. This has roughly tripled our speed
- On the side I build open-source PBIP governance tools: 95+ GitHub stars across 5 repositories
- Before BI, over ten years in supply chain and logistics operations: Samsung SDS, GXO Logistics, and more
Each of these came from a real governance problem at IKEA scale. The portfolio has a case study for every one: the problem, the approach, and what changed.
| Repository | What it does | Stars |
|---|---|---|
| pbip-documenter | Generates semantic model documentation from PBIP metadata |  |
| pbip-lineage-explorer | Visualizes end-to-end data lineage across models |  |
| isHiddenInViewMode | Bulk toggles visual visibility for governance control |  |
| pbip-impact-analyzer | Analyzes change impact before refactoring semantic models |  |
| pbip_model_lenz | Python PBIP analyzer (on PyPI): one graph, two readings for BI devs and data engineers |  |
I like comparing notes with teams running Power BI and Microsoft Fabric at enterprise scale. If you are working through a Fabric migration, a PBIR transition, or semantic models that AI can answer from, let's talk. The portfolio has the details, the tools, and the numbers.
