Take back control of your Power BI projects.
Audit, reverse engineering, recovery after a vendor leaves, optimisation and managed support for Power BI. I work on complex, international, business-critical environments, to stabilise, harden and extend the life of your reports.
Your reports are business-critical. And yet, the environment is no longer tenable.
I step in exactly when control of an inherited Power BI estate has been lost, and every passing day makes the recovery riskier.
The vendor is gone
You have inherited a Power BI estate with no proper handover, no contact, no up-to-date documentation.
The model has become opaque
Nobody knows exactly what each measure computes, or where the numbers on screen really come from.
Performance is dropping
Reports lag, refreshes get fragile, some visuals time out or display errors.
The numbers no longer match
Figures stop reconciling between reports, and nobody can explain why.
No usable documentation
Sources, flows and dependencies live nowhere. Every change becomes a jump into the unknown.
Reports are business-critical
Executive, finance, operations: these dashboards cannot fail. The margin for error is razor-thin.
Four services to recover, stabilise and sustain your BI projects.
Audit & reverse engineering
An independent diagnosis of your Power BI estate: data sources, models, measures, gateway, refresh, security. Risk map and concrete action plan.
Learn moreRecovery & stabilisation
Pick up an existing project after a vendor leaves or an incident. Restore confidence in the numbers, document, and harden for the long run.
Learn moreManaged support (TMA)
A senior BI hand on retainer: corrective and adaptive maintenance, evolutions, on-call coverage. Predictable budget, known commitments.
Learn moreData, ERP & SQL
Fix what feeds Power BI: SQL pipelines, ERP extraction, data quality, Python scripting. Reports are only as good as the data underneath.
Learn moreSenior expertise built for critical Power BI environments.
Power BI rarely fails on its own. The fix usually lives upstream: in the SQL layer, the ERP extraction, the data quality, or the modelling. I cover the whole chain so root causes get addressed, not symptoms.
A six-step approach, built for high-risk environments.
No big bang. We start from what exists, we stabilise, we document, then we optimise. At every step, you keep visibility and control.
Framing & access
Understand the stakes, the critical reports, the stakeholders. Secure access to tenants, workspaces, datasets, sources. Define scope and deliverables.
Audit & mapping
Reverse engineer the model, dataflows, DAX measures and dependencies. Map flows and risks. Clear, readable findings for both business and IT.
Stabilisation
Fix blocking anomalies, harden refreshes, secure access. The environment has to be tenable before any optimisation.
Optimisation & rationalisation
DAX and Power Query refactor, dataset rationalisation, performance, governance. We strip the debt that was slowing the team down.
Documentation & hand-over
Lasting technical and business documentation. Your team can maintain, evolve, explain. No more opaque dependency.
Managed support & follow-up
Long-term corrective and adaptive maintenance: new metrics, monitoring, user support, refreshes, targeted evolutions.
Used to multi-country organisations and their real friction points.
My engagements happen in contexts where several subsidiaries coexist, with consolidated reporting to harden despite local discrepancies.
Multilingual subsidiaries
Reports and labels to keep consistent across French, English, Italian, German, Japanese.
Time zones & fiscal calendars
Refreshes to orchestrate across zones, different fiscal calendars, shifted closing dates.
Currencies & FX rates
Conversions, average rates, closing rates, consolidated indicators without drift.
Heterogeneous sources
Local ERPs, country-specific instances, different formats, all to reconcile cleanly.

A few lines is enough: context, scope, criticality, known deadlines. From there we scope the right kind of engagement together: audit, recovery, managed support, or a one-off.
