About Julien

✨ Need a quick replacement? Reinforcement for year-end closing? A project to unblock? A team to strengthen immediately? I can help.

With over 15 years of experience, including more than 10 years subcontracting for a Big Four (PwC), I work in the following areas:

✅ Operational reinforcement & projects: ramp-up, process structuring, project management, optimization and standardization of methods.
✅ ERP AMOA SAP FICO Functional Consultant: I secure your projects, clarify business needs, and ensure proper tool adoption (UAT scripts, PDP/PA, ...)
✅ Transition Management: immediate takeover of key positions (Senior Management Controller, Financial Controller, Management Control Manager, ...).

🎯 My specialty: transforming data into decisions.
Excel, Access, VBA, Power BI… I make numbers speak and provide dashboards that accelerate action.

🎯 Excellent interpersonal and collaboration skills — proof: a mission extended for 4 years with the last client.

📩 Contact me to discuss your needs — I can also share feedback and references from my recent clients.
