I'm Jonathan — a Belgium-based freelance data engineer & architect. I help you build data platforms tailored to your business based on real-world experience.
End-to-end data solutions — from raw data to faster decisions
Designing scalable data models choosing the right techniques ranging from Kimball to Lakehouse patterns. Solid foundations evolve with your business.
Robust ETL/ELT pipelines with Azure Data Factory, Databricks, and SAP integration. Data that flows optimally and predictable.
Ensuring your data is trusted, owned, well-documented, and AI-ready.
Deep expertise in SAP BW and HANA. Bridging the gap between legacy SAP landscapes and modern cloud platforms.
The technologies I work with regularly
With over a decade of experience in enterprise data platforms, I bridge the gap between business needs and technical solutions. Technology choices should serve your goals — not the other way around.
No two companies are alike. That's why every solution I design is tailored to fit your specific landscape, team, and ambitions. Whether you're modernizing a legacy stack or building from scratch, I help you make the right choices for your environment.
I believe in data you can trust, architectures grounded in real experience, and solutions that grow with your business.
