About Guillaume

🎯 AI Expert | Fullstack Developer | CTO & Tech Leader
🧠 Combining technical expertise and business vision for high-impact projects

Graduated with a master's degree in computer science with a specialization in artificial intelligence, my career has led me to explore several cutting-edge technological fields. I first worked for 2 years in fullstack web development, then dived into the blockchain universe for 2 years, before returning to my primary passion: AI, which I have been practicing for 3 years now as a co-founder and CTO.

✅ What I bring to you:

A triple skill set: AI, Blockchain, and Web Development

Solid experience in technical leadership, team management, and project steering

A sharp business vision that allows me to align technical strategy with your business challenges

An ability to design, develop, and deliver complete, innovative, and scalable solutions

I am currently seeking freelance assignments that allow me to leverage this rich and cross-functional experience.
