About

Full-Stack & AI Engineer

I like building things from scratch and understanding every layer of the stack: raw sockets in C++, full-stack apps, and multi-agent systems on top of LLMs.

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.

This site is where I write about it as I build. Posts are in English and Spanish, and every English page has a plain-markdown copy for agents and other programs.
