Senior🎓
Top SchoolHugo Janssen is a seasoned Business Intelligence Developer and Azure data professional with over a decade of focused experience delivering cloud-native analytics, Power BI reporting, and data engineering solutions across public and private sectors in the Netherlands. He blends hands-on skills in Synapse, Data Factory, PySpark, DAX and CI/CD automation with a disciplined approach to data quality and governance, having implemented Great Expectations checks and Bicep/DevOps pipelines. Hugo has repeatedly translated complex regulatory and financial requirements into auditable reporting—most recently for a Dutch pension fund and previously for NS’s financial dashboards and a €3.5bn revenue forecasting product. As a freelancer he pairs practical engineering (ETL, REST APIs, delta lakehouse) with visualization craft, and his background in ECM and large-scale BI migrations gives him an unusual edge in bridging operational systems and analytics. Based in Maarsbergen, he combines academic computer science training with pragmatic delivery, often improving model accuracy and UX while simplifying downstream maintenance.
