Hello

I'm Jeroen

Senior Data Analyst and Power BI Developer

Services

1. Power BI Report Development & Optimization

Translating complex business inquiries into fully operational, enterprise-grade reports that teams actually love to use. Whether building from scratch or diagnosing existing setups, I eliminate performance bottlenecks to keep your reporting fast, responsive, and efficient.

2. AI-Ready Semantic Modelling

Capturing your specific business logic within robust, reusable semantic models (data models, relationships, and advanced DAX). I ensure you stop reinventing the wheel with disconnected reports, establishing a single source of truth that is fully optimized and primed for AI integration.

3. Data Storytelling & Bespoke Visuals

Most dashboards fail on adoption, not data. I design interfaces rooted in cognitive psychology principles to speed up insight discovery. When standard charts fall short, I develop custom visuals tailored precisely to your requirements using HTML/CSS, D3.js, and Python.

4. Cloud Data Analytics & Data Marts

For data challenges that go beyond the dashboard layer. I write optimized queries, clean raw datasets, and structure them into clean data marts and 'golden layers'--delivering seamless analytics across both Databricks and Microsoft Fabric.

5. Advanced Analytics & Deep-Dive Research

For complex business questions that go far beyond standard operational dashboards. Utilizing Python and SQL, I run deep-dive research projects to extract actionable statistical truths. I help you solve high-impact puzzles, such as uncovering the underlying drivers of customer churn or calculating exactly how external variables like weather anomalies impact your sales performance.

6. Fabric & Power BI Architecture & Governance

Setting up and maintaining what happens behind the curtain. From workspace tenant settings and strict security implementation to deep-dive health checks across your Fabric and Power BI environments, ensuring your platform remains highly performant, secure, and manageable as your organization scales.

About Me

As a driven data analyst and Power BI developer, I believe that teamwork, organization, and flexibility are the key ingredients for success. My core skills include data analysis, data visualization engineering, and data discovery and modeling, using AI where it has its place. While business decisions can often be based on gut feeling, why not back them up with data?

Data only drives action when it connects with human cognition. I design data visualizations based on cognitive design principles, making insights instinctual, decisions faster, and impact bigger.
