After operational experience in marketing (advertising manager at Havas advertising, market research and reporting manager at Alcon/Nestlé, creation of 5 direct marketing entities at La Poste, marketing department manager in a regional directorate then a business agency at France Telecom), I was an internal auditor for 5 years at the audit department of the Orange group where I participated in the implementation of Sarbanes-Oxley (Sox) law and internal control compliant with COSO. I completed the entire IFACI (IIA) training cycle, passed the CIA, and carried out "full scope" missions in all types of operational entities of the operator in France. Then, I was a consultant at Sofrecom where I carried out numerous missions for telecom operators (in 27 countries in total): audit and process improvement missions, pure compliance missions (vs. US anti-corruption law), creation of an audit department for an operator, recruitment, training and launch of the first missions, development of crisis plans in complex issues, business process audits, HR audits... My last experience (2025): audit of a leading American IoT company to verify the robustness of its business continuity, change management, capacity management, and incident management processes on behalf of its client, the Orange group.
