Strategic finance expert for high-stakes transitions
French-swiss integrations and large industrial operations
I deliver hands-on CFO experience to SMEs and international firms requiring immediate operational cleanup, audit readiness, and strategic financial governance.







30+ Years
Cross-border financial architecture experience
Why now?
Companies operating across French and Swiss borders deal with unique pressures to merge different work cultures, financial accounting needs, and complex legal rules while managing multimillion-dollar projects.
These businesses in industrial sectors need a veteran perspective capable of implementing strategies and ERP systems that work at international scale and in diverse regulatory environments. My services are for these companies that have a need for expert handling or resolving cross-border friction.
- Cross-border firm stalling on French-Swiss integrations.
- Industrial group facing complex cross-border compliance.
- Construction firm losing project financial control.

Bouygues nigeria limited
Plant department
financial controlling
turnaround
I overhauled the plant department for a leading European construction subsidiary in Nigeria to eliminate chronic financial leakage.
By bypassing obsolete software and under-skilled reporting, I established rigid governance that turned an opaque cost center into a flagship model of operational efficiency.
Dana incorporated
Crisis stabilized,
compliance restored
Following a major European restructuring, Dana faced multiple litigations, audit blockages, and broken internal communication threatening U.S. consolidated reporting. A 10-month interim mission delivered a full diagnostic, resolved all blocking points, and rebuilt trust between regional and EMEA headquarters.
ADV construction (GCC group)
Reporting reconciled,
cash recovered
After GCC acquired this swiss construction specialist, misaligned accounting methods and improper cut-offs led to unforecasted losses and a CHF 700K variance.
A 12-month interim mission bridged cultural gaps, reconciled the balance sheet, and extended treasury visibility — restoring group alignment.
Antenna international
Banking simplified,
costs reduced
Antenna’s EMEA operations spanned 24 countries with fragmented banking, poor cash visibility, and elevated fees — limiting financial agility for this cultural technology leader.
A pragmatic hybrid model consolidated primary banking with Deutsche Bank across four key markets while centralizing high-value procurement through the UK.
Energizer / edgewell personal care
Spin-off delivered
ahead schedule
A tax-free spin-off required full separation of French and Swiss financial operations into two independent public companies, with simultaneous SSC migration to the UK.
A structured three-milestone roadmap — diagnostic, transition, and balance sheet separation — was executed across €130M combined revenue with zero major incidents.
From crisis
to financial control
We bypass bloated consulting reports. This is a battle-tested roadmap to assess your vulnerabilities, execute structural fixes, and exit cleanly.

Tactical execution
Six-step framework is built to immediately stabilize operations
Rapid diagnosis with on-site analysis
I start with a focused assessment of your situation, conducted on-site across the key areas that determine performance. This covers your organisation and processes, the reliability of your financial reporting, and how decisions are made within your team. The objective is to identify what is broken, what is misunderstood, and what requires immediate action.
Prioritized action plan
You receive a structured and practical roadmap based on this assessment. Immediate issues that can be resolved quickly are addressed first, while deeper structural problems are clearly defined with a path to resolution. Every action is tied to a concrete business outcome.
Hands on execution with your team
I integrate directly into your operations to lead execution. This includes stabilizing reporting, restoring financial control, and implementing systems that support scale. The focus remains on delivering tangible improvements, not theoretical recommendations
Continuous progress tracking
Progress is monitored through regular reviews to maintain full visibility on results, priorities, and risks. At key stages, we reassess timelines and scope to ensure the engagement remains aligned with your operational reality.
Knowledge transfer and clean handover
Before the end of the assignment, your team is fully equipped to sustain the improvements delivered. Processes are clarified, tools are added and financial visibility is maintained without ongoing external dependency.
Measurable closure
The engagement concludes with a clear evaluation of results. Reporting becomes reliable, cash control is strengthened, and the finance function is positioned to support growth and future operations.
