Work: Projects I've Designed and Optimized
Before advising you, I apply my methods to my own projects. Here are the main ones, all public and verifiable.
Arachnide SEO Spider
A free, open-source SEO crawler. I designed, developed and published it on GitHub, and I regularly improve it with feedback from the French-speaking SEO community.
Vigie
An open-source AI visibility tracker, published in October 2026.
DelfOnline
An e-learning platform for DELF, DALF and TCF exam preparation. I designed it, developed it with AI tools, launched it and optimized it for search on my own.
GustinAI
A website and AI training offering for businesses, designed from the outset to be cited by AI engines, in French, Spanish and English.
The Claude AI Bible
The English edition of La Bible de Claude AI, a reference guide to Claude AI and an Amazon best-seller, published in six languages: French, Spanish, German, Italian, Portuguese and English.
thierrygustin.com
This very website: rebuilt with Lovable using server rendering, in three languages, with complete structured data, accessible and optimized for AI engines. View its source code: it's all there.
What about client case studies?
I only publish verifiable results with my clients' consent. I'll show you concrete examples during our first call.
