About
Maxime Goelff
Data Analyst and independent Power BI consultant (MgLytics), I work in parallel within the Data team at Wallonie Finances Expertises (WFE), where I develop and maintain financial steering tools for the Walloon Region.
My approach: Passionate about decoding complexity, I rely on my dual experience in financial economics and data analysis to bridge the gap between numbers and real-world decisions. Dedicated to fostering clear and honest dialogue with my clients, I prioritize the rigorous cross-checking of data to deliver robust and objective empirical insights. My goal is to build a shared understanding to address organizational challenges and translate business needs into operational solutions.
Based in Namur, I work with organisations looking to make better decisions through their data: public sector, non-profits, SMEs or large enterprises.

Your questions
Frequently Asked Questions
What services does MgLytics offer?
Founded by Maxime Goelff, MgLytics offers technical and strategic data consulting services. Our interventions cover Business Intelligence (Power BI dashboard creation), data architecture (pipeline automation and ERP integration), financial analysis, as well as the pragmatic integration of Artificial Intelligence (RAG, LLM) into your business processes.
Do you offer training on Power BI and Artificial Intelligence?
Yes. Beyond developing tools, we provide tailored training and coaching to make your teams autonomous. Whether you want to master data modelling in Power BI, learn DAX, or understand how to integrate generative AI to solve your challenges, we design programmes adapted to your operational reality.
In which regions do you operate?
Based in the Namur province, we operate on-site within organisations located across the Walloon Region, Brussels, and the Hauts-de-France region. To ensure flexible and responsive collaboration, all our consulting and training missions can also be conducted remotely or in a hybrid format.
Why combine technical expertise with public finance?
Mastering technical data tools (DAX, Power Query, AI) coupled with strong business experience (SAP, budgetary accounting) allows us to create dashboards that are directly actionable. We translate your financial challenges into genuine decision-support solutions for both the public and private sectors.
I have scattered data (Excel, business software), can you help me?
Absolutely. A large part of our work involves automating the consolidation of multiple sources. We design pipelines (ETL) that extract, cleanse, and secure your data to feed a single central model, guaranteeing a "single version of the truth" for your reporting.
How do you transform scattered and unstructured data into management tools?
This is the core expertise of MgLytics, already proven with top management in the Walloon administration. We capture, cleanse, and cross-reference your data, whether it comes from multiple or unstructured sources. We then transform it into intuitive dashboards (Power BI) coupled with pragmatic AI. Our solutions cater to a dual audience: a macro, executive overview for management, and a detailed, practical view for operational teams.
