Description

Excel training and data advice at an academic level, from the perspective of a business engineer.

Many companies use Excel, but few companies get the most out of it. As an expert in Operations Research, I combine in-depth technical insight with a sharp focus on business processes and efficiency.

After years of complex research (including optimization at KU Leuven and AI applications at KMS), I now focus with PivotXpert.be on making data skills accessible to professionals. I am also still active as a Guest Lecturer in Quantitative Policy Methods at KU Leuven.

What makes my approach unique? I am not a standard IT trainer. I think like an engineer: how can this process be faster, more error-free, and smarter? Whether it's a financial department losing hours on copy-pasting, or engineers who need to model data.

My Expertise:

📊 Advanced Excel & BI (PivotXpert)

- Power Query (ETL): Automated data import and cleaning.

- Power Pivot (DAX): Advanced data models and establishing relationships.

- Automation: Eliminating time-consuming tasks so your team can focus on analysis.

🧮 Data Science & Analytics

- Operations Research: Optimization problems and simulation models.

- Python & Machine Learning: For when Excel is no longer sufficient (experience with complex datasets and detection algorithms).

- Statistics: Clear interpretation of numbers and uncertainties.

🎓 Education & Didactics As a guest lecturer, I am used to explaining complex subject matter (Mathematics, Statistics, OR) clearly and understandably to diverse target groups. I offer:

- In-company group training sessions (B2B).

- 1-on-1 coaching for analysts and managers.

- Consultancy on a project basis.

Looking for a trainer who looks beyond the formulas and thinks along with your business logic? Let's connect!
