Valencia Marathon, 2025 — mile 22, still smiling.
Currently Senior AI Engineer at Checkmk · Co-founder at DatAIMed

Hi, I'm Matteo.
I work on language models, mostly.

I'm an AI engineer. Right now that means shipping AI features and enablement at Checkmk, co-founding DatAIMed, and maintaining a small open-source library called ErisForge. I like shipping things, writing about what I learn, and the occasional side project that gets out of hand.
