Maxime Goelff

Transforming complex and scattered data into clear, tailor-made decision-making levers: that's the goal of my support. My profile is based on a dual requirement: a deep understanding of strategic issues and uncompromising technical rigor. An economist by training, specializing in public finance, I combine business vision with development expertise. This duality allows me to design tools that are not only aesthetically pleasing but also rigorously precise and adapted to your operational realities. I position myself as the direct link between your complex data and your decision-making objectives.

Technical Expertise & Scalability

I have in-depth mastery of the Power BI ecosystem to deliver robust and high-performance solutions:

- Power Query (M) & DAX: Development of optimized ETL flows and sophisticated measures for reliable performance indicators (KPIs).

- Dataflows: Implementation of scalable architectures to ensure the performance of your reports, even on massive data volumes.

- AI & Efficiency: Active use of LLM models and prompt engineering to accelerate development while minimizing technical biases and hallucinations.

Analytical Methodology

My approach involves breaking down complex challenges into segmented problems to provide targeted solutions. I bridge the common gap between business profiles, who sometimes lack technical tools, and pure developers, who may overlook end-user needs.

Background & Achievements

Designer of the "WinSight" application (budgetary and financial centralization for the Walloon Region covering the entire SEC 2010 European consolidation scope), I am involved in auditing existing solutions, migrating Excel reports, or creating complete dashboards. Based in Belgium, I carry out my complementary activity with a constant commitment to rigor, precision, and confidentiality.
