Back to original languageAbout Thierry
Hello,
Independent Telecoms Consultant and Project Manager, I support IT departments and business units in modernizing their critical communication infrastructures (VoIP, ToIP, CCaaS) and their transition to Full IP.
My expertise focuses on three major pillars:
1. Scoping and migration: Audit of the existing infrastructure, choice of architectures (SIP Trunk, FTTO/FTTH links) and management of complex multi-site migration projects.
2. CCaaS & Cloud Integration: Deployment and administration of Contact Center solutions (expert in Odigo / Pink Soda solution) and interfacing with collaborative tools like MS Teams.
3. "Move to Run": Securing flows, access management (SAML 2.0) and above all, structuring the transition to operations to ensure SLA compliance and reduce operational risks.
Accustomed to high-stakes environments and large accounts (TotalEnergies, VeePee, Foliateam), I ensure smooth cross-functional coordination between your business teams, IT, software vendors, and historical operators (Orange, SFR, Bouygues, Completel).
My preferred areas of intervention:
• Management of Telecoms & Networks deployment projects
• Migration of traditional architectures (T0/T2) to SIP Trunk
• Integration, configuration (IVR, agent profiles) and acceptance testing of CCaaS solutions
• Crisis management and service quality restoration (SLA / GTR)
Available for short-term scoping missions or large-scale deployment management. Let's meet to discuss your current challenges!
