campo-vivo — this portfolio
This site. A portfolio that is alive — the visitor's real hour, weather and moon light a calm, legible field — built with Astro, deployed on Cloudflare, with a small Voice running on Workers AI.
Full-stack GenAI app
A full-stack application (frontend and backend) built without prior knowledge of the stack, using advanced prompting as the main development tool.
