Experiments

Serchai serchai.com A search engine built on RAG and a mini-LLM, at near-zero cost. The thesis: retrieval is the most underrated part of AI — this is where I learn it deeply.
Trader Profesional traderprofesional.com Order-flow trading site maintained 100% by AI. The thesis: a niche media site can run without humans.
PaellaDoc paelladoc.com From PRD to end-to-end product — user stories, acceptance criteria, and a final video of the tests passing. The thesis: the time sink isn’t generating with AI, it’s validating its work.
LLM Engineer Club llmengineerclub.com A living LLM engineering course, free and community-maintained via pull requests. The thesis: courses go stale; a repo doesn’t.
Silicon Valley Confidential siliconvalleyconfidential.com Weekly executive intelligence on Silicon Valley, in Spanish. The experiment: a media outlet operated by agents.
Recetas para Manolo recetasparamanolo.com Weekly satire of the antimanager, in Spanish. The experiment: an authorial voice sustained by agents.
