About Serge

🚀 Program Director & IT Transition Manager

How I can help you:

  • I manage and secure your critical projects, providing rigorous cost, quality, and deadline management. I stop the bleeding, cauterize, and revive projects that are off track. But that's not all...

  • SMEs, Mid-caps: I bring your IT system back under control through adapted transition management.

For over 10 years, I have been working as a freelancer for SMEs, mid-caps, and large corporations to turn around, structure, and secure high-stakes programs as well as struggling IT systems. I step in where the stakes are high: strategic programs, complex transformations, multi-stakeholder, multi-country, or multi-ERP contexts.

Significant references:
  • Roquette Frère: took over the €6M Salesforce program which was already over budget in the first year.
  • Assurpeople.com: transition management following the IT Director's burnout (15 resources)
  • La Méta (GIE): took over the management of the IT system creation (€1.5M)
  • Thales: coaching the project manager to get a Third-Party Maintenance (TPM) back on track
  • Auchan: transition management of the textile purchasing domain (Oracle ERP, WMS, TXT), €2 billion in revenue
