Freelancer profile translated to English.

Description

Backend Python Developer | 7 years of experience | Hybrid availability

Trained in demanding environments — Société Générale and SNCF Gares & Connexions — I have developed technical rigor and a results-oriented culture that I wish to bring to new projects as a freelancer.

At Société Générale, I worked for 6 years on critical Python backend systems in an IAM (Identity & Access Management) context with ForgeRock, where security, reliability, and code quality are non-negotiable.

At SNCF Gares & Connexions, I co-built a conversational chatbot from scratch deployed on Messenger, used by over 10,000 travelers across France. A project managed end-to-end: architecture, Flask development, PostgreSQL, NLP, and real-time API integration.

🎯 What I'm looking for

I am now launching my freelance activity and seeking my first backend Python development mission. My goal is simple: to bring real technical value from day one, integrate quickly into your team, and build a long-term trusting relationship.
