// ABOUT Hi, I'm
Hi, I'm
Marc Mayol.
I'm an engineer and Tech Lead specialized in generative AI. For over six years I've worked with machine learning and AI, helping companies and technical teams take AI from the lab to production.
I'm as passionate about the technical side as I am about explaining it: that's why I give talks, train teams and share what I learn in my newsletter and blog. My obsession: making AI stop being a pretty demo and become something useful.

My story
My story
Ever since I was a kid growing up in Mallorca, I've had an insatiable curiosity for understanding how things work. I used to take apart toys, electronic devices and pretty much anything that landed in my hands, not to break them, but to uncover their inner workings and learn. That same curiosity is what eventually led me to become an engineer and, later on, to dedicate myself to the world of artificial intelligence.
Today, I'm an AI developer and educator. I combine technical development with teaching because I firmly believe that knowledge, when shared, multiplies. I'm passionate about creating solutions that truly work — ones that go beyond being flashy to become genuinely useful tools.
My content
I write articles, create content and take part in initiatives where AI isn't just a trend, but a purposeful tool. I'm especially interested in how intelligent agents can become useful, valuable and marketable products for businesses.
I keep learning every day, exploring new paths and sharing what I discover. If there's one thing I've learned along the way, it's that technology only makes sense when it improves people's lives.
Featured model
EsDrac-v1-7B
HUGGING FACEThe first language model that produces authentic Mallorcan (mallorquí) — with the salat article (es, sa, ses) and traditional expressions ("Això era i no era…"). Fine-tuned from Qwen2.5-7B-Instruct, trilingual (Mallorcan, Spanish and English) with agentic function-calling abilities. Named after the Es Drac de na Coca legend.
