Writing

Thoughts on data,
design & craft

I write about Power BI, Microsoft Fabric, visualization principles, and the craft of turning raw numbers into stories people care about.

01
Power BI
Why most Power BI dashboards fail (and how to fix yours)
The problem isn't the data — it's the design. A framework I use to audit and rebuild reports that people actually use.

02
Community
What running two Power BI User Groups taught me about community
Lessons from building data communities in Berlin and Athens — what works, what doesn't, and why it matters more than the tools.

Color in data visualization: less is almost always more
A practical guide to color theory for dashboard designers — when to use it, when to hold back, and why grey is your best friend.

Fabric
Upstream thinking: the architectural mindset Power BI developers need
An expanded take on my SQLBits talk — why performance problems in Power BI are almost always born upstream, not in the model.

About

Analyst. Speaker.
Community builder.

I'm Ioannis Philippides, a results-driven analytics professional based in Berlin, Germany, specializing in Power BI and Microsoft Fabric. I work across industries including consulting, marketing, insurance, and product — turning complex datasets into decisions people actually make.

Beyond the day job, I'm an active part of the global data community. I speak at international conferences — from PASS Data Community Summit in Seattle to SQLBits in London — and I organize the Berlin and Athens Power BI User Groups, creating local spaces where data professionals learn and connect.

I believe that data clarity is a communication skill, not just a technical one — and I bring that perspective to every talk, dashboard, and community session I run.
