Hi, I'm Christophe!
I'm currently working as a freelancer / fractional worker, specializing in Cybersecurity and AI.
During my career, I have held various positions:
- Unix sysadmin
- Cybersecurity engineer
- Network engineer
- Pentester
- Business continuity consultant
- Solopreneur in the wellness industry
- Software engineer
Also, I have lived off the grid (with fiber 🚀) for over 15 years.
About
I've been passionate about AI since college, my research project focused on multi-agent systems.
NLP (Natural Language Processing) in particular is a topic that has always fascinated me.
During spring-summer 2023, I created a creative writing tool using generative AI, based on multi-agents.
Then I worked on the MVP of a specialized assistant, in a professional setting, using RAG (Retrieval Augmented Generation) and fine tuning (QLoRA).
I created this site at the end of 2023 because my co-workers were interested in learning more about LLM (Large Language Model), and didn't know how to start.
I started writing an organized course, but the field of AI evolved so fast, the direction I had taken didn't make much sense after a few months.
So I restarted this site a year later, keeping the content that still makes sense, and leaving aside the idea of doing an organized course.
I decided to use this site as a personal website, the old-fashioned way, where I share technical knowledge, and depending on my mood, my thoughts on the tech world.
