20 years across the full call path, from the network to the LLM.
I spent 10 years in network & security, then 12 years designing and rolling out international contact centers across up to 25 countries. Today I design and build real-time Voice AI: voice agents, SIP/WebRTC orchestration and contact center automation, delivered through an industrialized AI-agent development workflow. I bridge business, infrastructure and code.

Experience
Solocal (PagesJaunes) Contact Center Tech Lead
Paris area, Feb 2024 - 2026
France’s leading local digital marketing company for small businesses. I own the technical side of the contact center (customer care, retention, telesales, production) on Diabolocom, coupled with Salesforce.
- Raised outbound reachability by 10-25% through ARCEP-compliant mobile caller ID, callback strategies and automated campaigns.
- Cut idle agent time by up to 30% by rolling out multichannel (voice/SMS) campaigns in predictive mode.
- Rolled out Diabolocom Mobile, a hybrid setup where the same mobile numbers work both on physical handsets and in the contact center’s outbound campaigns, in line with ARCEP rules.
- Brought AI into the call flows: LLMs embedded in IVRs, AI-driven quality monitoring and voice analytics.
- Orchestrated configuration across systems through AI-agent development (Claude Code, Grok): scripts that keep the contact center, CRM and business applications in sync via API, plus call data analysis (reachability, performance, quality).
- Automated callbacks on unanswered calls and industrialized phone contact for several business processes (order management, high-value accounts, web production).
- Orchestrated data flows from the contact center to BI, CRM, QM and business applications.
- Reduced recurring license and service costs by 15%.
- Ran the team’s JIRA backlog and day-to-day operations.
