AI engineer with business fluency

I'm César García Cabeza, a senior freelance AI consultant. I come from data science and now build agentic AI that companies actually use. No hype, no empty promises: engineering tied to outcomes.

César García Cabeza works at the uncommon overlap between serious engineering and business language. He understands the code, and he understands what moves a leadership team.

Andorra is his base and his trust anchor. He works remotely with teams in any time zone, but he operates from a stable, serious framework.
