What I'm looking for

I'm looking for BI/data roles using Microsoft BI/Power BI where I can build data models, design ETL, deliver dashboards, and collaborate with stakeholders.

I'm a Business Intelligence developer with extensive experience building BI solutions using the Microsoft BI stack, Power BI, and Microsoft Fabric. I have delivered both legacy and prototype solutions in the HR domain, supporting multiple Visma companies and internal departments.

My background includes backend SQL programming, ETL development, SSIS/SSRS/SSAS implementations and database design across insurance, HR and healthcare-related ERP systems. I consistently focus on data integration, architecture and clear visualization to support operational and strategic decisions.

I have freelance experience and maintain a technical blog where I present dashboards, COVID-related analytics and practical BI examples. I have also created bespoke MS Access applications for municipalities, kindergartens and university events to meet specific reporting requirements.

I value pragmatic, well-architected data solutions, clear reporting and collaboration with stakeholders. I seek roles where I can apply analytical skills, data modeling and Microsoft BI tooling to drive actionable insights and improve business processes.
