Full-Stack & AI Engineer

I'm a 17-year-old full-stack & AI engineer in Buenos Aires. I build AI agents, robots, and web apps.

Right now I'm building C3PO, a project to give Claude a Unitree G1 humanoid body. The last thing I shipped was Lendy, an AI microcredit lender built at an Anthropic hackathon. I do most of my work in the terminal and Vim.

Work

  • C3PO

    Giving Claude a Unitree G1 humanoid body: an MCP server, an agent backend, and a chat interface. It started in Isaac Sim and has run on real hardware since July 2026.

  • hush

    A single Rust binary that keeps your .env encrypted inside the repo. Recipients are GitHub usernames, so there is no key exchange to run.

  • Lendy

    An AI microcredit lender, built over a weekend at an Anthropic hackathon.
