Freelancer profile translated to English.

Description

Hello, I am a senior developer with a focus on AI agent solutions.

I assist with digital transformation by conducting an in-depth audit of the company and its processes to identify high-ROI actions.

I code and master the project end-to-end (fine tuning, monitoring...).

I can assist with n8n / nocode or custom solutions, adapted to your needs.

In particular, I can create evaluation frameworks for agentic systems based on industry best practices (Berkeley course)

I can also handle hosting in France with DPA and RGPD compliance.

As a developer for over 9 years, I can manage complex systems and take on a part-time lead/CTO role.

Furthermore, I have solid experience in security and can adapt to projects with confidentiality needs (security, AI agent hosted in France, DPA, RGPD...).

Thank you Bertrand for this particularly enriching collaboration in creating our agentic tool for writing procedures. Throughout the project, you scrupulously respected the specifications while demonstrating great responsiveness and constant availability. The fluidity with which you managed this project was remarkable: the use of Slack as an on-demand communication channel greatly facilitated our interaction and allowed for quick adjustments at each stage. This collaborative work environment, combined with your seriousness and expertise, was decisive in the success of this project. Well done Bertrand, and looking forward to working together again!
