AI Agent

Ask my AI anything.

The fastest way to know if my background fits your role. This chat is a Retrieval-Augmented agent grounded on my full resume, LinkedIn history, and project details — built on Anthropic’s Claude.

It runs on a Cloudflare Worker proxying to the Anthropic API, with my knowledge base injected into the system prompt. Yes — I built it. It’s a working demo of what I do.

  • Grounded answers from my actual work history
  • Answers in English, Portuguese, or Spanish
  • Honest about what it doesn’t know — won’t make things up
  • Will hand you off to the real Fabio when needed
