REC CORP
Senior Power BI consultant — available

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.

The situation I run into

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.

Expertise

Senior 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.

Method

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.

01

Framing & access

Understand the stakes, the critical reports, the stakeholders. Secure access to tenants, workspaces, datasets, sources. Define scope and deliverables.

02

Audit & mapping

Reverse engineer the model, dataflows, DAX measures and dependencies. Map flows and risks. Clear, readable findings for both business and IT.

03

Stabilisation

Fix blocking anomalies, harden refreshes, secure access. The environment has to be tenable before any optimisation.

04

Optimisation & rationalisation

DAX and Power Query refactor, dataset rationalisation, performance, governance. We strip the debt that was slowing the team down.

05

Documentation & hand-over

Lasting technical and business documentation. Your team can maintain, evolve, explain. No more opaque dependency.

06

Managed support & follow-up

Long-term corrective and adaptive maintenance: new metrics, monitoring, user support, refreshes, targeted evolutions.

International environments

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.
