This portfolio: a website built with AI from start to finish

The design, content and code of this very site, directed by me with AI as a co-pilot: an Astro architecture with content collections editable without touching code, three languages (es/ca/en), a real contact form, and a production deployment. My first development project using this method — and the most direct proof of how I apply AI to a concrete problem.

Real AI chatbot for the portfolio

A conversational assistant built into this very site: it answers questions about my experience, projects and training using Claude (Anthropic), with the site's real content assembled as context on every request — no extra backend or vector database. Includes cost safeguards (message limit per conversation, message length cap and response token cap) and a serverless deployment on Vercel. Try it right now in the bubble at the bottom right.
