About David

AI Agents Developer | n8n | Make | PowerPlatform | NoCode Applications

AI Agent and intelligent automation specialist, I help companies and freelancers save time, reduce costs, and increase productivity through tailor-made solutions.
With several successful projects at Generali, Enedis, and Renault, I have developed agents capable of acting autonomously, interacting with users, and executing complex processes, integrated directly into business tools.

My biggest project is the development of a voice agent for Generali, currently live and handling 1.2 million calls per year.

Examples of AI agents I have already created:
- 24/7 Customer Service Agent – automatically responds to customers, manages tickets, and escalates if needed.
- Sales Prospecting Agent – detects, contacts, and qualifies prospects via email/LinkedIn.
- HR Agent – pre-qualifies candidates, schedules interviews, and centralizes CVs.
- Financial Agent – analyzes invoices, tracks payments, and sends reminders.
- Training Agent – trains on internal documentation and coaches employees in real-time.
- Voice Agent (Voice bot) that acts as a switchboard

What I offer:
- Custom AI Agent Development (OpenAI, Gemini, Mistral…)
- Advanced Automations with n8n, Make, Zapier
- Intelligent Chatbots connected to your business tools
- Strategic Consulting and Support
- Training and Coaching to learn how to create and deploy your own AI agents

Key Tools:
Agents & Automations: n8n, Make, Zapier, OpenAI, Gemini, Mistral

Complementary Applications: Bubble, FlutterFlow

Web: Webflow, Wordpress

In a very short period, David managed to bring a real boost and new energy to the development of our virtual agent. His expertise in Low Code/No Code technologies (n8n, etc.) and his mastery of Voice Agent tools (like Vapi) allowed him to quickly grasp Cognigy. Finally, beyond the technical skills, his deep understanding of business challenges and his ability to clearly present his progress to senior stakeholders make him a particularly well-rounded profile with whom it is very pleasant to work.
